Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80980, here are decompositions:

17 + 80963 = 80980
47 + 80933 = 80980
71 + 80909 = 80980
83 + 80897 = 80980
131 + 80849 = 80980
149 + 80831 = 80980
191 + 80789 = 80980
197 + 80783 = 80980

Showing the first eight; more decompositions exist.
