Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545502, here are decompositions:
- 3 + 31545499 = 31545502
- 101 + 31545401 = 31545502
- 173 + 31545329 = 31545502
- 179 + 31545323 = 31545502
- 269 + 31545233 = 31545502
- 281 + 31545221 = 31545502
- 311 + 31545191 = 31545502
- 383 + 31545119 = 31545502
Showing the first eight; more decompositions exist.
