Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516228, here are decompositions:
- 71 + 31516157 = 31516228
- 89 + 31516139 = 31516228
- 167 + 31516061 = 31516228
- 239 + 31515989 = 31516228
- 347 + 31515881 = 31516228
- 461 + 31515767 = 31516228
- 509 + 31515719 = 31516228
- 587 + 31515641 = 31516228
Showing the first eight; more decompositions exist.
