Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294970638, here are decompositions:
- 71 + 4294970567 = 4294970638
- 107 + 4294970531 = 4294970638
- 449 + 4294970189 = 4294970638
- 557 + 4294970081 = 4294970638
- 641 + 4294969997 = 4294970638
- 659 + 4294969979 = 4294970638
- 809 + 4294969829 = 4294970638
- 857 + 4294969781 = 4294970638
Showing the first eight; more decompositions exist.
