Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11688, here are decompositions:

7 + 11681 = 11688
11 + 11677 = 11688
31 + 11657 = 11688
67 + 11621 = 11688
71 + 11617 = 11688
101 + 11587 = 11688
109 + 11579 = 11688
137 + 11551 = 11688

Showing the first eight; more decompositions exist.
