Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28660, here are decompositions:

3 + 28657 = 28660
11 + 28649 = 28660
17 + 28643 = 28660
29 + 28631 = 28660
41 + 28619 = 28660
53 + 28607 = 28660
89 + 28571 = 28660
101 + 28559 = 28660

Showing the first eight; more decompositions exist.
