Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294974838, here are decompositions:
- 101 + 4294974737 = 4294974838
- 107 + 4294974731 = 4294974838
- 191 + 4294974647 = 4294974838
- 197 + 4294974641 = 4294974838
- 239 + 4294974599 = 4294974838
- 257 + 4294974581 = 4294974838
- 269 + 4294974569 = 4294974838
- 311 + 4294974527 = 4294974838
Showing the first eight; more decompositions exist.
