Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545484, here are decompositions:
- 83 + 31545401 = 31545484
- 167 + 31545317 = 31545484
- 197 + 31545287 = 31545484
- 251 + 31545233 = 31545484
- 263 + 31545221 = 31545484
- 293 + 31545191 = 31545484
- 401 + 31545083 = 31545484
- 461 + 31545023 = 31545484
Showing the first eight; more decompositions exist.
