Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544772, here are decompositions:
- 13 + 31544759 = 31544772
- 23 + 31544749 = 31544772
- 53 + 31544719 = 31544772
- 59 + 31544713 = 31544772
- 199 + 31544573 = 31544772
- 211 + 31544561 = 31544772
- 229 + 31544543 = 31544772
- 239 + 31544533 = 31544772
Showing the first eight; more decompositions exist.
