Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613228, here are decompositions:
- 37 + 31613191 = 31613228
- 109 + 31613119 = 31613228
- 277 + 31612951 = 31613228
- 337 + 31612891 = 31613228
- 397 + 31612831 = 31613228
- 499 + 31612729 = 31613228
- 601 + 31612627 = 31613228
- 607 + 31612621 = 31613228
Showing the first eight; more decompositions exist.
