Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28610, here are decompositions:

3 + 28607 = 28610
7 + 28603 = 28610
13 + 28597 = 28610
19 + 28591 = 28610
31 + 28579 = 28610
37 + 28573 = 28610
61 + 28549 = 28610
73 + 28537 = 28610

Showing the first eight; more decompositions exist.
