Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8686664, here are decompositions:

3 + 8686661 = 8686664
13 + 8686651 = 8686664
97 + 8686567 = 8686664
163 + 8686501 = 8686664
193 + 8686471 = 8686664
367 + 8686297 = 8686664
373 + 8686291 = 8686664
457 + 8686207 = 8686664

Showing the first eight; more decompositions exist.
