Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1040688, here are decompositions:
- 17 + 1040671 = 1040688
- 29 + 1040659 = 1040688
- 31 + 1040657 = 1040688
- 37 + 1040651 = 1040688
- 59 + 1040629 = 1040688
- 107 + 1040581 = 1040688
- 109 + 1040579 = 1040688
- 157 + 1040531 = 1040688
Showing the first eight; more decompositions exist.
