Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294976878, here are decompositions:
- 11 + 4294976867 = 4294976878
- 239 + 4294976639 = 4294976878
- 251 + 4294976627 = 4294976878
- 359 + 4294976519 = 4294976878
- 431 + 4294976447 = 4294976878
- 461 + 4294976417 = 4294976878
- 557 + 4294976321 = 4294976878
- 617 + 4294976261 = 4294976878
Showing the first eight; more decompositions exist.
