Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8684990, here are decompositions:

7 + 8684983 = 8684990
31 + 8684959 = 8684990
43 + 8684947 = 8684990
79 + 8684911 = 8684990
229 + 8684761 = 8684990
277 + 8684713 = 8684990
487 + 8684503 = 8684990
571 + 8684419 = 8684990

Showing the first eight; more decompositions exist.
