Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294976866, here are decompositions:
- 149 + 4294976717 = 4294976866
- 227 + 4294976639 = 4294976866
- 239 + 4294976627 = 4294976866
- 317 + 4294976549 = 4294976866
- 347 + 4294976519 = 4294976866
- 419 + 4294976447 = 4294976866
- 449 + 4294976417 = 4294976866
- 647 + 4294976219 = 4294976866
Showing the first eight; more decompositions exist.
