Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544800, here are decompositions:
- 17 + 31544783 = 31544800
- 29 + 31544771 = 31544800
- 41 + 31544759 = 31544800
- 83 + 31544717 = 31544800
- 227 + 31544573 = 31544800
- 239 + 31544561 = 31544800
- 257 + 31544543 = 31544800
- 269 + 31544531 = 31544800
Showing the first eight; more decompositions exist.
