Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28616, here are decompositions:

13 + 28603 = 28616
19 + 28597 = 28616
37 + 28579 = 28616
43 + 28573 = 28616
67 + 28549 = 28616
79 + 28537 = 28616
103 + 28513 = 28616
139 + 28477 = 28616

Showing the first eight; more decompositions exist.
