Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545568, here are decompositions:
- 167 + 31545401 = 31545568
- 239 + 31545329 = 31545568
- 251 + 31545317 = 31545568
- 269 + 31545299 = 31545568
- 281 + 31545287 = 31545568
- 347 + 31545221 = 31545568
- 449 + 31545119 = 31545568
- 599 + 31544969 = 31545568
Showing the first eight; more decompositions exist.
