Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12980, here are decompositions:

7 + 12973 = 12980
13 + 12967 = 12980
61 + 12919 = 12980
73 + 12907 = 12980
127 + 12853 = 12980
139 + 12841 = 12980
151 + 12829 = 12980
157 + 12823 = 12980

Showing the first eight; more decompositions exist.
