Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681980, here are decompositions:

3 + 8681977 = 8681980
11 + 8681969 = 8681980
23 + 8681957 = 8681980
149 + 8681831 = 8681980
191 + 8681789 = 8681980
311 + 8681669 = 8681980
317 + 8681663 = 8681980
401 + 8681579 = 8681980

Showing the first eight; more decompositions exist.
