Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523660, here are decompositions:
- 13 + 31523647 = 31523660
- 61 + 31523599 = 31523660
- 139 + 31523521 = 31523660
- 193 + 31523467 = 31523660
- 199 + 31523461 = 31523660
- 241 + 31523419 = 31523660
- 313 + 31523347 = 31523660
- 331 + 31523329 = 31523660
Showing the first eight; more decompositions exist.
