Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28646, here are decompositions:

3 + 28643 = 28646
19 + 28627 = 28646
43 + 28603 = 28646
67 + 28579 = 28646
73 + 28573 = 28646
97 + 28549 = 28646
109 + 28537 = 28646
199 + 28447 = 28646

Showing the first eight; more decompositions exist.
