Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82980, here are decompositions:

17 + 82963 = 82980
41 + 82939 = 82980
67 + 82913 = 82980
89 + 82891 = 82980
97 + 82883 = 82980
167 + 82813 = 82980
181 + 82799 = 82980
193 + 82787 = 82980

Showing the first eight; more decompositions exist.
