Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11680, here are decompositions:

3 + 11677 = 11680
23 + 11657 = 11680
47 + 11633 = 11680
59 + 11621 = 11680
83 + 11597 = 11680
101 + 11579 = 11680
131 + 11549 = 11680
191 + 11489 = 11680

Showing the first eight; more decompositions exist.
