Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544572, here are decompositions:
- 11 + 31544561 = 31544572
- 29 + 31544543 = 31544572
- 41 + 31544531 = 31544572
- 179 + 31544393 = 31544572
- 359 + 31544213 = 31544572
- 383 + 31544189 = 31544572
- 401 + 31544171 = 31544572
- 419 + 31544153 = 31544572
Showing the first eight; more decompositions exist.
