Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646732, here are decompositions:

11 + 8646721 = 8646732
13 + 8646719 = 8646732
23 + 8646709 = 8646732
151 + 8646581 = 8646732
173 + 8646559 = 8646732
229 + 8646503 = 8646732
331 + 8646401 = 8646732
433 + 8646299 = 8646732

Showing the first eight; more decompositions exist.
