Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294973878, here are decompositions:
- 11 + 4294973867 = 4294973878
- 47 + 4294973831 = 4294973878
- 227 + 4294973651 = 4294973878
- 347 + 4294973531 = 4294973878
- 359 + 4294973519 = 4294973878
- 401 + 4294973477 = 4294973878
- 491 + 4294973387 = 4294973878
- 557 + 4294973321 = 4294973878
Showing the first eight; more decompositions exist.
