Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508822, here are decompositions:
- 31 + 31508791 = 31508822
- 109 + 31508713 = 31508822
- 139 + 31508683 = 31508822
- 151 + 31508671 = 31508822
- 313 + 31508509 = 31508822
- 379 + 31508443 = 31508822
- 463 + 31508359 = 31508822
- 619 + 31508203 = 31508822
Showing the first eight; more decompositions exist.
