Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545228, here are decompositions:
- 7 + 31545221 = 31545228
- 17 + 31545211 = 31545228
- 37 + 31545191 = 31545228
- 47 + 31545181 = 31545228
- 109 + 31545119 = 31545228
- 131 + 31545097 = 31545228
- 137 + 31545091 = 31545228
- 167 + 31545061 = 31545228
Showing the first eight; more decompositions exist.
