Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545244, here are decompositions:
- 11 + 31545233 = 31545244
- 23 + 31545221 = 31545244
- 53 + 31545191 = 31545244
- 281 + 31544963 = 31545244
- 461 + 31544783 = 31545244
- 587 + 31544657 = 31545244
- 683 + 31544561 = 31545244
- 701 + 31544543 = 31545244
Showing the first eight; more decompositions exist.
