Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678772, here are decompositions:
- 13 + 8678759 = 8678772
- 19 + 8678753 = 8678772
- 23 + 8678749 = 8678772
- 31 + 8678741 = 8678772
- 59 + 8678713 = 8678772
- 71 + 8678701 = 8678772
- 73 + 8678699 = 8678772
- 79 + 8678693 = 8678772
Showing the first eight; more decompositions exist.
