Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545156, here are decompositions:
- 37 + 31545119 = 31545156
- 59 + 31545097 = 31545156
- 73 + 31545083 = 31545156
- 89 + 31545067 = 31545156
- 107 + 31545049 = 31545156
- 193 + 31544963 = 31545156
- 233 + 31544923 = 31545156
- 257 + 31544899 = 31545156
Showing the first eight; more decompositions exist.
