Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7986, here are decompositions:

23 + 7963 = 7986
37 + 7949 = 7986
53 + 7933 = 7986
59 + 7927 = 7986
67 + 7919 = 7986
79 + 7907 = 7986
103 + 7883 = 7986
107 + 7879 = 7986

Showing the first eight; more decompositions exist.
