Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43638, here are decompositions:
- 5 + 43633 = 43638
- 11 + 43627 = 43638
- 29 + 43609 = 43638
- 31 + 43607 = 43638
- 41 + 43597 = 43638
- 47 + 43591 = 43638
- 59 + 43579 = 43638
- 61 + 43577 = 43638
Showing the first eight; more decompositions exist.
