Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681984, here are decompositions:

7 + 8681977 = 8681984
43 + 8681941 = 8681984
61 + 8681923 = 8681984
127 + 8681857 = 8681984
163 + 8681821 = 8681984
277 + 8681707 = 8681984
397 + 8681587 = 8681984
607 + 8681377 = 8681984

Showing the first eight; more decompositions exist.
