Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544516, here are decompositions:
- 7 + 31544509 = 31544516
- 193 + 31544323 = 31544516
- 337 + 31544179 = 31544516
- 349 + 31544167 = 31544516
- 439 + 31544077 = 31544516
- 463 + 31544053 = 31544516
- 613 + 31543903 = 31544516
- 643 + 31543873 = 31544516
Showing the first eight; more decompositions exist.
