Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294974478, here are decompositions:
- 191 + 4294974287 = 4294974478
- 239 + 4294974239 = 4294974478
- 251 + 4294974227 = 4294974478
- 401 + 4294974077 = 4294974478
- 419 + 4294974059 = 4294974478
- 461 + 4294974017 = 4294974478
- 479 + 4294973999 = 4294974478
- 491 + 4294973987 = 4294974478
Showing the first eight; more decompositions exist.
