Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545134, here are decompositions:
- 37 + 31545097 = 31545134
- 43 + 31545091 = 31545134
- 67 + 31545067 = 31545134
- 73 + 31545061 = 31545134
- 193 + 31544941 = 31545134
- 211 + 31544923 = 31545134
- 277 + 31544857 = 31545134
- 307 + 31544827 = 31545134
Showing the first eight; more decompositions exist.
