Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294974988, here are decompositions:
- 71 + 4294974917 = 4294974988
- 107 + 4294974881 = 4294974988
- 251 + 4294974737 = 4294974988
- 257 + 4294974731 = 4294974988
- 347 + 4294974641 = 4294974988
- 389 + 4294974599 = 4294974988
- 419 + 4294974569 = 4294974988
- 461 + 4294974527 = 4294974988
Showing the first eight; more decompositions exist.
