Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678912, here are decompositions:
- 13 + 8678899 = 8678912
- 19 + 8678893 = 8678912
- 61 + 8678851 = 8678912
- 79 + 8678833 = 8678912
- 139 + 8678773 = 8678912
- 163 + 8678749 = 8678912
- 199 + 8678713 = 8678912
- 211 + 8678701 = 8678912
Showing the first eight; more decompositions exist.
