Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536632, here are decompositions:
- 3 + 31536629 = 31536632
- 19 + 31536613 = 31536632
- 103 + 31536529 = 31536632
- 151 + 31536481 = 31536632
- 229 + 31536403 = 31536632
- 241 + 31536391 = 31536632
- 271 + 31536361 = 31536632
- 409 + 31536223 = 31536632
Showing the first eight; more decompositions exist.
