Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531060, here are decompositions:
- 3 + 31531057 = 31531060
- 59 + 31531001 = 31531060
- 83 + 31530977 = 31531060
- 101 + 31530959 = 31531060
- 167 + 31530893 = 31531060
- 227 + 31530833 = 31531060
- 233 + 31530827 = 31531060
- 263 + 31530797 = 31531060
Showing the first eight; more decompositions exist.
