Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544730, here are decompositions:
- 11 + 31544719 = 31544730
- 13 + 31544717 = 31544730
- 17 + 31544713 = 31544730
- 73 + 31544657 = 31544730
- 157 + 31544573 = 31544730
- 179 + 31544551 = 31544730
- 197 + 31544533 = 31544730
- 199 + 31544531 = 31544730
Showing the first eight; more decompositions exist.
