Answer 1

int i;int lowerlimit;int upperlimit;onSelfEvent(load){lowerlimit=9;upperlimit=20;for(i=lowerlimit;i<=upperlimit;i++){if (i%2==0){_root.Show(i);}} }int j;int N;int primes = 0;int nn=0;int left=0;int right=0;function Show(number ) {isprime = new Array; N = number;for(j=2;j<N;j++){isprime[j] = "1";}}for(j=2;j<=N;j++){if(i*i<N){if(isprime[j]=="1"){for(l=j;l<=N;l++){isprime[i * j] = "0" ;} }}}for(j=2;j<N;j++){if(isprime[j]=="1"){primes = primes + 1;}}list = new Array[primes] for(j=0;j<N;j++){if(isprime[j]=="1"){nn = nn + 1;list[nn] = "i";}}left = 0;right = primes - 1;while (left <= right){if(list[left] + list[right] = N){break;else if (list[left] + list[right] < N){left = left + 1;elseright = right - 1;}}}if (list[left] + list[right] = N){trace(N + " = " + list[left] + " + " + list[right]);}else{trace(N + " not expressible as sum of two primes");}return 0;}
