Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545010, here are decompositions:
- 41 + 31544969 = 31545010
- 47 + 31544963 = 31545010
- 131 + 31544879 = 31545010
- 191 + 31544819 = 31545010
- 227 + 31544783 = 31545010
- 239 + 31544771 = 31545010
- 251 + 31544759 = 31545010
- 293 + 31544717 = 31545010
Showing the first eight; more decompositions exist.
