Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43688, here are decompositions:
- 19 + 43669 = 43688
- 37 + 43651 = 43688
- 61 + 43627 = 43688
- 79 + 43609 = 43688
- 97 + 43591 = 43688
- 109 + 43579 = 43688
- 277 + 43411 = 43688
- 367 + 43321 = 43688
Showing the first eight; more decompositions exist.
