Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681604, here are decompositions:

17 + 8681587 = 8681604
37 + 8681567 = 8681604
97 + 8681507 = 8681604
101 + 8681503 = 8681604
131 + 8681473 = 8681604
137 + 8681467 = 8681604
157 + 8681447 = 8681604
227 + 8681377 = 8681604

Showing the first eight; more decompositions exist.
