Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78712, here are decompositions:
- 5 + 78707 = 78712
- 59 + 78653 = 78712
- 89 + 78623 = 78712
- 173 + 78539 = 78712
- 233 + 78479 = 78712
- 311 + 78401 = 78712
- 401 + 78311 = 78712
- 479 + 78233 = 78712
Showing the first eight; more decompositions exist.
