Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7716, here are decompositions:
- 13 + 7703 = 7716
- 17 + 7699 = 7716
- 29 + 7687 = 7716
- 43 + 7673 = 7716
- 47 + 7669 = 7716
- 67 + 7649 = 7716
- 73 + 7643 = 7716
- 109 + 7607 = 7716
Showing the first eight; more decompositions exist.
