Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 76980, here are decompositions:

17 + 76963 = 76980
19 + 76961 = 76980
31 + 76949 = 76980
37 + 76943 = 76980
61 + 76919 = 76980
67 + 76913 = 76980
73 + 76907 = 76980
97 + 76883 = 76980

Showing the first eight; more decompositions exist.
