Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536680, here are decompositions:
- 67 + 31536613 = 31536680
- 73 + 31536607 = 31536680
- 151 + 31536529 = 31536680
- 181 + 31536499 = 31536680
- 199 + 31536481 = 31536680
- 277 + 31536403 = 31536680
- 283 + 31536397 = 31536680
- 367 + 31536313 = 31536680
Showing the first eight; more decompositions exist.
