Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544770, here are decompositions:
- 11 + 31544759 = 31544770
- 53 + 31544717 = 31544770
- 113 + 31544657 = 31544770
- 197 + 31544573 = 31544770
- 227 + 31544543 = 31544770
- 239 + 31544531 = 31544770
- 353 + 31544417 = 31544770
- 557 + 31544213 = 31544770
Showing the first eight; more decompositions exist.
