Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28612, here are decompositions:

5 + 28607 = 28612
41 + 28571 = 28612
53 + 28559 = 28612
71 + 28541 = 28612
113 + 28499 = 28612
149 + 28463 = 28612
173 + 28439 = 28612
179 + 28433 = 28612

Showing the first eight; more decompositions exist.
