Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545056, here are decompositions:
- 7 + 31545049 = 31545056
- 157 + 31544899 = 31545056
- 199 + 31544857 = 31545056
- 229 + 31544827 = 31545056
- 307 + 31544749 = 31545056
- 337 + 31544719 = 31545056
- 523 + 31544533 = 31545056
- 547 + 31544509 = 31545056
Showing the first eight; more decompositions exist.
