Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712240, here are decompositions:
- 7 + 8712233 = 8712240
- 11 + 8712229 = 8712240
- 13 + 8712227 = 8712240
- 59 + 8712181 = 8712240
- 67 + 8712173 = 8712240
- 71 + 8712169 = 8712240
- 73 + 8712167 = 8712240
- 83 + 8712157 = 8712240
Showing the first eight; more decompositions exist.
