Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8612980, here are decompositions:

11 + 8612969 = 8612980
23 + 8612957 = 8612980
53 + 8612927 = 8612980
107 + 8612873 = 8612980
149 + 8612831 = 8612980
179 + 8612801 = 8612980
227 + 8612753 = 8612980
251 + 8612729 = 8612980

Showing the first eight; more decompositions exist.
