Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545166, here are decompositions:
- 47 + 31545119 = 31545166
- 83 + 31545083 = 31545166
- 197 + 31544969 = 31545166
- 347 + 31544819 = 31545166
- 383 + 31544783 = 31545166
- 449 + 31544717 = 31545166
- 509 + 31544657 = 31545166
- 593 + 31544573 = 31545166
Showing the first eight; more decompositions exist.
