Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61716, here are decompositions:
- 13 + 61703 = 61716
- 29 + 61687 = 61716
- 43 + 61673 = 61716
- 59 + 61657 = 61716
- 73 + 61643 = 61716
- 79 + 61637 = 61716
- 89 + 61627 = 61716
- 103 + 61613 = 61716
Showing the first eight; more decompositions exist.
