Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28608, here are decompositions:

5 + 28603 = 28608
11 + 28597 = 28608
17 + 28591 = 28608
29 + 28579 = 28608
37 + 28571 = 28608
59 + 28549 = 28608
61 + 28547 = 28608
67 + 28541 = 28608

Showing the first eight; more decompositions exist.
