Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679040, here are decompositions:
- 3 + 8679037 = 8679040
- 89 + 8678951 = 8679040
- 101 + 8678939 = 8679040
- 107 + 8678933 = 8679040
- 113 + 8678927 = 8679040
- 137 + 8678903 = 8679040
- 257 + 8678783 = 8679040
- 263 + 8678777 = 8679040
Showing the first eight; more decompositions exist.
