Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544310, here are decompositions:
- 13 + 31544297 = 31544310
- 29 + 31544281 = 31544310
- 89 + 31544221 = 31544310
- 97 + 31544213 = 31544310
- 103 + 31544207 = 31544310
- 131 + 31544179 = 31544310
- 139 + 31544171 = 31544310
- 157 + 31544153 = 31544310
Showing the first eight; more decompositions exist.
