Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 76986, here are decompositions:

23 + 76963 = 76986
37 + 76949 = 76986
43 + 76943 = 76986
67 + 76919 = 76986
73 + 76913 = 76986
79 + 76907 = 76986
103 + 76883 = 76986
113 + 76873 = 76986

Showing the first eight; more decompositions exist.
