Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28650, here are decompositions:

7 + 28643 = 28650
19 + 28631 = 28650
23 + 28627 = 28650
29 + 28621 = 28650
31 + 28619 = 28650
43 + 28607 = 28650
47 + 28603 = 28650
53 + 28597 = 28650

Showing the first eight; more decompositions exist.
