Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294974820, here are decompositions:
- 83 + 4294974737 = 4294974820
- 89 + 4294974731 = 4294974820
- 167 + 4294974653 = 4294974820
- 173 + 4294974647 = 4294974820
- 179 + 4294974641 = 4294974820
- 239 + 4294974581 = 4294974820
- 251 + 4294974569 = 4294974820
- 293 + 4294974527 = 4294974820
Showing the first eight; more decompositions exist.
