Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8663684, here are decompositions:

31 + 8663653 = 8663684
163 + 8663521 = 8663684
181 + 8663503 = 8663684
223 + 8663461 = 8663684
283 + 8663401 = 8663684
373 + 8663311 = 8663684
613 + 8663071 = 8663684
661 + 8663023 = 8663684

Showing the first eight; more decompositions exist.
