Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8684972, here are decompositions:

13 + 8684959 = 8684972
31 + 8684941 = 8684972
61 + 8684911 = 8684972
151 + 8684821 = 8684972
211 + 8684761 = 8684972
613 + 8684359 = 8684972
631 + 8684341 = 8684972
643 + 8684329 = 8684972

Showing the first eight; more decompositions exist.
