Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545294, here are decompositions:
- 7 + 31545287 = 31545294
- 61 + 31545233 = 31545294
- 73 + 31545221 = 31545294
- 83 + 31545211 = 31545294
- 103 + 31545191 = 31545294
- 113 + 31545181 = 31545294
- 197 + 31545097 = 31545294
- 211 + 31545083 = 31545294
Showing the first eight; more decompositions exist.
