Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23638, here are decompositions:
- 5 + 23633 = 23638
- 11 + 23627 = 23638
- 29 + 23609 = 23638
- 71 + 23567 = 23638
- 89 + 23549 = 23638
- 101 + 23537 = 23638
- 107 + 23531 = 23638
- 179 + 23459 = 23638
Showing the first eight; more decompositions exist.
