Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031688, here are decompositions:
- 11 + 1031677 = 1031688
- 19 + 1031669 = 1031688
- 59 + 1031629 = 1031688
- 79 + 1031609 = 1031688
- 127 + 1031561 = 1031688
- 139 + 1031549 = 1031688
- 157 + 1031531 = 1031688
- 167 + 1031521 = 1031688
Showing the first eight; more decompositions exist.
