Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545412, here are decompositions:
- 5 + 31545407 = 31545412
- 11 + 31545401 = 31545412
- 83 + 31545329 = 31545412
- 89 + 31545323 = 31545412
- 113 + 31545299 = 31545412
- 179 + 31545233 = 31545412
- 191 + 31545221 = 31545412
- 293 + 31545119 = 31545412
Showing the first eight; more decompositions exist.
