Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8677680, here are decompositions:
- 17 + 8677663 = 8677680
- 29 + 8677651 = 8677680
- 73 + 8677607 = 8677680
- 103 + 8677577 = 8677680
- 127 + 8677553 = 8677680
- 197 + 8677483 = 8677680
- 199 + 8677481 = 8677680
- 223 + 8677457 = 8677680
Showing the first eight; more decompositions exist.
