Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7712, here are decompositions:
- 13 + 7699 = 7712
- 31 + 7681 = 7712
- 43 + 7669 = 7712
- 73 + 7639 = 7712
- 109 + 7603 = 7712
- 139 + 7573 = 7712
- 151 + 7561 = 7712
- 163 + 7549 = 7712
Showing the first eight; more decompositions exist.
