Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508460, here are decompositions:
- 7 + 31508453 = 31508460
- 17 + 31508443 = 31508460
- 43 + 31508417 = 31508460
- 97 + 31508363 = 31508460
- 101 + 31508359 = 31508460
- 131 + 31508329 = 31508460
- 149 + 31508311 = 31508460
- 173 + 31508287 = 31508460
Showing the first eight; more decompositions exist.
