Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28662, here are decompositions:

5 + 28657 = 28662
13 + 28649 = 28662
19 + 28643 = 28662
31 + 28631 = 28662
41 + 28621 = 28662
43 + 28619 = 28662
59 + 28603 = 28662
71 + 28591 = 28662

Showing the first eight; more decompositions exist.
