Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536398, here are decompositions:
- 7 + 31536391 = 31536398
- 37 + 31536361 = 31536398
- 211 + 31536187 = 31536398
- 337 + 31536061 = 31536398
- 349 + 31536049 = 31536398
- 379 + 31536019 = 31536398
- 457 + 31535941 = 31536398
- 571 + 31535827 = 31536398
Showing the first eight; more decompositions exist.
