Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72712, here are decompositions:
- 5 + 72707 = 72712
- 11 + 72701 = 72712
- 23 + 72689 = 72712
- 41 + 72671 = 72712
- 89 + 72623 = 72712
- 179 + 72533 = 72712
- 251 + 72461 = 72712
- 281 + 72431 = 72712
Showing the first eight; more decompositions exist.
