Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523700, here are decompositions:
- 31 + 31523669 = 31523700
- 41 + 31523659 = 31523700
- 53 + 31523647 = 31523700
- 67 + 31523633 = 31523700
- 101 + 31523599 = 31523700
- 163 + 31523537 = 31523700
- 179 + 31523521 = 31523700
- 223 + 31523477 = 31523700
Showing the first eight; more decompositions exist.
