Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681566, here are decompositions:

17 + 8681549 = 8681566
53 + 8681513 = 8681566
59 + 8681507 = 8681566
83 + 8681483 = 8681566
137 + 8681429 = 8681566
197 + 8681369 = 8681566
353 + 8681213 = 8681566
359 + 8681207 = 8681566

Showing the first eight; more decompositions exist.
