Goldbach decomposition

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.
