Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8684618, here are decompositions:

31 + 8684587 = 8684618
97 + 8684521 = 8684618
139 + 8684479 = 8684618
157 + 8684461 = 8684618
181 + 8684437 = 8684618
199 + 8684419 = 8684618
211 + 8684407 = 8684618
277 + 8684341 = 8684618

Showing the first eight; more decompositions exist.
