Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545258, here are decompositions:
- 37 + 31545221 = 31545258
- 47 + 31545211 = 31545258
- 67 + 31545191 = 31545258
- 139 + 31545119 = 31545258
- 167 + 31545091 = 31545258
- 191 + 31545067 = 31545258
- 197 + 31545061 = 31545258
- 257 + 31545001 = 31545258
Showing the first eight; more decompositions exist.
