Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545070, here are decompositions:
- 3 + 31545067 = 31545070
- 47 + 31545023 = 31545070
- 101 + 31544969 = 31545070
- 107 + 31544963 = 31545070
- 191 + 31544879 = 31545070
- 251 + 31544819 = 31545070
- 311 + 31544759 = 31545070
- 353 + 31544717 = 31545070
Showing the first eight; more decompositions exist.
