Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545370, here are decompositions:
- 41 + 31545329 = 31545370
- 47 + 31545323 = 31545370
- 53 + 31545317 = 31545370
- 71 + 31545299 = 31545370
- 83 + 31545287 = 31545370
- 137 + 31545233 = 31545370
- 149 + 31545221 = 31545370
- 179 + 31545191 = 31545370
Showing the first eight; more decompositions exist.
