Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294976938, here are decompositions:
- 71 + 4294976867 = 4294976938
- 311 + 4294976627 = 4294976938
- 359 + 4294976579 = 4294976938
- 389 + 4294976549 = 4294976938
- 401 + 4294976537 = 4294976938
- 419 + 4294976519 = 4294976938
- 491 + 4294976447 = 4294976938
- 521 + 4294976417 = 4294976938
Showing the first eight; more decompositions exist.
