Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541482, here are decompositions:
- 53 + 31541429 = 31541482
- 83 + 31541399 = 31541482
- 239 + 31541243 = 31541482
- 353 + 31541129 = 31541482
- 431 + 31541051 = 31541482
- 443 + 31541039 = 31541482
- 461 + 31541021 = 31541482
- 491 + 31540991 = 31541482
Showing the first eight; more decompositions exist.
