Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40628, here are decompositions:
- 19 + 40609 = 40628
- 31 + 40597 = 40628
- 37 + 40591 = 40628
- 97 + 40531 = 40628
- 109 + 40519 = 40628
- 157 + 40471 = 40628
- 199 + 40429 = 40628
- 241 + 40387 = 40628
Showing the first eight; more decompositions exist.
