Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742768, here are decompositions:
- 29 + 8742739 = 8742768
- 79 + 8742689 = 8742768
- 131 + 8742637 = 8742768
- 191 + 8742577 = 8742768
- 197 + 8742571 = 8742768
- 227 + 8742541 = 8742768
- 239 + 8742529 = 8742768
- 257 + 8742511 = 8742768
Showing the first eight; more decompositions exist.
