Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8684978, here are decompositions:

19 + 8684959 = 8684978
31 + 8684947 = 8684978
37 + 8684941 = 8684978
67 + 8684911 = 8684978
157 + 8684821 = 8684978
349 + 8684629 = 8684978
457 + 8684521 = 8684978
499 + 8684479 = 8684978

Showing the first eight; more decompositions exist.
