Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536918, here are decompositions:
- 47 + 31536871 = 31536918
- 71 + 31536847 = 31536918
- 89 + 31536829 = 31536918
- 97 + 31536821 = 31536918
- 199 + 31536719 = 31536918
- 211 + 31536707 = 31536918
- 311 + 31536607 = 31536918
- 367 + 31536551 = 31536918
Showing the first eight; more decompositions exist.
