Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545104, here are decompositions:
- 7 + 31545097 = 31545104
- 13 + 31545091 = 31545104
- 37 + 31545067 = 31545104
- 43 + 31545061 = 31545104
- 103 + 31545001 = 31545104
- 163 + 31544941 = 31545104
- 181 + 31544923 = 31545104
- 277 + 31544827 = 31545104
Showing the first eight; more decompositions exist.
