Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31490746, here are decompositions:
- 5 + 31490741 = 31490746
- 17 + 31490729 = 31490746
- 59 + 31490687 = 31490746
- 113 + 31490633 = 31490746
- 137 + 31490609 = 31490746
- 173 + 31490573 = 31490746
- 179 + 31490567 = 31490746
- 239 + 31490507 = 31490746
Showing the first eight; more decompositions exist.
