Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545206, here are decompositions:
- 109 + 31545097 = 31545206
- 139 + 31545067 = 31545206
- 157 + 31545049 = 31545206
- 283 + 31544923 = 31545206
- 307 + 31544899 = 31545206
- 349 + 31544857 = 31545206
- 379 + 31544827 = 31545206
- 457 + 31544749 = 31545206
Showing the first eight; more decompositions exist.
