Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15600, here are decompositions:

17 + 15583 = 15600
19 + 15581 = 15600
31 + 15569 = 15600
41 + 15559 = 15600
59 + 15541 = 15600
73 + 15527 = 15600
89 + 15511 = 15600
103 + 15497 = 15600

Showing the first eight; more decompositions exist.
