Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681636, here are decompositions:

13 + 8681623 = 8681636
97 + 8681539 = 8681636
163 + 8681473 = 8681636
277 + 8681359 = 8681636
349 + 8681287 = 8681636
373 + 8681263 = 8681636
547 + 8681089 = 8681636
577 + 8681059 = 8681636

Showing the first eight; more decompositions exist.
