Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545022, here are decompositions:
- 53 + 31544969 = 31545022
- 59 + 31544963 = 31545022
- 239 + 31544783 = 31545022
- 251 + 31544771 = 31545022
- 263 + 31544759 = 31545022
- 449 + 31544573 = 31545022
- 461 + 31544561 = 31545022
- 479 + 31544543 = 31545022
Showing the first eight; more decompositions exist.
