Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28634, here are decompositions:
- 3 + 28631 = 28634
- 7 + 28627 = 28634
- 13 + 28621 = 28634
- 31 + 28603 = 28634
- 37 + 28597 = 28634
- 43 + 28591 = 28634
- 61 + 28573 = 28634
- 97 + 28537 = 28634
Showing the first eight; more decompositions exist.
