Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544550, here are decompositions:
- 7 + 31544543 = 31544550
- 17 + 31544533 = 31544550
- 19 + 31544531 = 31544550
- 41 + 31544509 = 31544550
- 157 + 31544393 = 31544550
- 179 + 31544371 = 31544550
- 227 + 31544323 = 31544550
- 239 + 31544311 = 31544550
Showing the first eight; more decompositions exist.
