Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545378, here are decompositions:
- 5 + 31545373 = 31545378
- 47 + 31545331 = 31545378
- 61 + 31545317 = 31545378
- 79 + 31545299 = 31545378
- 157 + 31545221 = 31545378
- 167 + 31545211 = 31545378
- 197 + 31545181 = 31545378
- 281 + 31545097 = 31545378
Showing the first eight; more decompositions exist.
