Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545164, here are decompositions:
- 67 + 31545097 = 31545164
- 73 + 31545091 = 31545164
- 97 + 31545067 = 31545164
- 103 + 31545061 = 31545164
- 163 + 31545001 = 31545164
- 223 + 31544941 = 31545164
- 241 + 31544923 = 31545164
- 307 + 31544857 = 31545164
Showing the first eight; more decompositions exist.
