Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11646, here are decompositions:

13 + 11633 = 11646
29 + 11617 = 11646
53 + 11593 = 11646
59 + 11587 = 11646
67 + 11579 = 11646
97 + 11549 = 11646
127 + 11519 = 11646
149 + 11497 = 11646

Showing the first eight; more decompositions exist.
