Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545106, here are decompositions:
- 23 + 31545083 = 31545106
- 83 + 31545023 = 31545106
- 137 + 31544969 = 31545106
- 227 + 31544879 = 31545106
- 347 + 31544759 = 31545106
- 389 + 31544717 = 31545106
- 449 + 31544657 = 31545106
- 563 + 31544543 = 31545106
Showing the first eight; more decompositions exist.
