Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80982, here are decompositions:

19 + 80963 = 80982
29 + 80953 = 80982
53 + 80929 = 80982
59 + 80923 = 80982
71 + 80911 = 80982
73 + 80909 = 80982
149 + 80833 = 80982
151 + 80831 = 80982

Showing the first eight; more decompositions exist.
