Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545122, here are decompositions:
- 3 + 31545119 = 31545122
- 31 + 31545091 = 31545122
- 61 + 31545061 = 31545122
- 73 + 31545049 = 31545122
- 181 + 31544941 = 31545122
- 199 + 31544923 = 31545122
- 223 + 31544899 = 31545122
- 373 + 31544749 = 31545122
Showing the first eight; more decompositions exist.
