Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15630, here are decompositions:

11 + 15619 = 15630
23 + 15607 = 15630
29 + 15601 = 15630
47 + 15583 = 15630
61 + 15569 = 15630
71 + 15559 = 15630
79 + 15551 = 15630
89 + 15541 = 15630

Showing the first eight; more decompositions exist.
