Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11676, here are decompositions:

19 + 11657 = 11676
43 + 11633 = 11676
59 + 11617 = 11676
79 + 11597 = 11676
83 + 11593 = 11676
89 + 11587 = 11676
97 + 11579 = 11676
127 + 11549 = 11676

Showing the first eight; more decompositions exist.
