Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545174, here are decompositions:
- 83 + 31545091 = 31545174
- 107 + 31545067 = 31545174
- 113 + 31545061 = 31545174
- 151 + 31545023 = 31545174
- 173 + 31545001 = 31545174
- 211 + 31544963 = 31545174
- 233 + 31544941 = 31545174
- 251 + 31544923 = 31545174
Showing the first eight; more decompositions exist.
