Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294974778, here are decompositions:
- 41 + 4294974737 = 4294974778
- 47 + 4294974731 = 4294974778
- 131 + 4294974647 = 4294974778
- 137 + 4294974641 = 4294974778
- 179 + 4294974599 = 4294974778
- 197 + 4294974581 = 4294974778
- 251 + 4294974527 = 4294974778
- 491 + 4294974287 = 4294974778
Showing the first eight; more decompositions exist.
