Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545126, here are decompositions:
- 7 + 31545119 = 31545126
- 29 + 31545097 = 31545126
- 43 + 31545083 = 31545126
- 59 + 31545067 = 31545126
- 103 + 31545023 = 31545126
- 157 + 31544969 = 31545126
- 163 + 31544963 = 31545126
- 227 + 31544899 = 31545126
Showing the first eight; more decompositions exist.
