Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536256, here are decompositions:
- 29 + 31536227 = 31536256
- 53 + 31536203 = 31536256
- 239 + 31536017 = 31536256
- 317 + 31535939 = 31536256
- 347 + 31535909 = 31536256
- 503 + 31535753 = 31536256
- 509 + 31535747 = 31536256
- 599 + 31535657 = 31536256
Showing the first eight; more decompositions exist.
