Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8684684, here are decompositions:

97 + 8684587 = 8684684
163 + 8684521 = 8684684
181 + 8684503 = 8684684
223 + 8684461 = 8684684
277 + 8684407 = 8684684
577 + 8684107 = 8684684
607 + 8684077 = 8684684
661 + 8684023 = 8684684

Showing the first eight; more decompositions exist.
