Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11628, here are decompositions:

7 + 11621 = 11628
11 + 11617 = 11628
31 + 11597 = 11628
41 + 11587 = 11628
79 + 11549 = 11628
101 + 11527 = 11628
109 + 11519 = 11628
131 + 11497 = 11628

Showing the first eight; more decompositions exist.
