Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545456, here are decompositions:
- 17 + 31545439 = 31545456
- 83 + 31545373 = 31545456
- 113 + 31545343 = 31545456
- 127 + 31545329 = 31545456
- 139 + 31545317 = 31545456
- 157 + 31545299 = 31545456
- 223 + 31545233 = 31545456
- 337 + 31545119 = 31545456
Showing the first eight; more decompositions exist.
