Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545300, here are decompositions:
- 13 + 31545287 = 31545300
- 67 + 31545233 = 31545300
- 79 + 31545221 = 31545300
- 89 + 31545211 = 31545300
- 109 + 31545191 = 31545300
- 181 + 31545119 = 31545300
- 233 + 31545067 = 31545300
- 239 + 31545061 = 31545300
Showing the first eight; more decompositions exist.
