Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8684880, here are decompositions:

7 + 8684873 = 8684880
19 + 8684861 = 8684880
59 + 8684821 = 8684880
97 + 8684783 = 8684880
109 + 8684771 = 8684880
167 + 8684713 = 8684880
181 + 8684699 = 8684880
223 + 8684657 = 8684880

Showing the first eight; more decompositions exist.
