Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544732, here are decompositions:
- 13 + 31544719 = 31544732
- 19 + 31544713 = 31544732
- 181 + 31544551 = 31544732
- 199 + 31544533 = 31544732
- 223 + 31544509 = 31544732
- 409 + 31544323 = 31544732
- 421 + 31544311 = 31544732
- 601 + 31544131 = 31544732
Showing the first eight; more decompositions exist.
