Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679648, here are decompositions:
- 7 + 8679641 = 8679648
- 31 + 8679617 = 8679648
- 41 + 8679607 = 8679648
- 67 + 8679581 = 8679648
- 97 + 8679551 = 8679648
- 149 + 8679499 = 8679648
- 191 + 8679457 = 8679648
- 199 + 8679449 = 8679648
Showing the first eight; more decompositions exist.
