Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77980, here are decompositions:

3 + 77977 = 77980
11 + 77969 = 77980
29 + 77951 = 77980
47 + 77933 = 77980
113 + 77867 = 77980
131 + 77849 = 77980
167 + 77813 = 77980
179 + 77801 = 77980

Showing the first eight; more decompositions exist.
