Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544656, here are decompositions:
- 83 + 31544573 = 31544656
- 113 + 31544543 = 31544656
- 239 + 31544417 = 31544656
- 263 + 31544393 = 31544656
- 293 + 31544363 = 31544656
- 359 + 31544297 = 31544656
- 443 + 31544213 = 31544656
- 449 + 31544207 = 31544656
Showing the first eight; more decompositions exist.
