Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536560, here are decompositions:
- 31 + 31536529 = 31536560
- 61 + 31536499 = 31536560
- 79 + 31536481 = 31536560
- 157 + 31536403 = 31536560
- 163 + 31536397 = 31536560
- 199 + 31536361 = 31536560
- 337 + 31536223 = 31536560
- 373 + 31536187 = 31536560
Showing the first eight; more decompositions exist.
