Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729080, here are decompositions:

23 + 8729057 = 8729080
29 + 8729051 = 8729080
47 + 8729033 = 8729080
137 + 8728943 = 8729080
179 + 8728901 = 8729080
197 + 8728883 = 8729080
257 + 8728823 = 8729080
293 + 8728787 = 8729080

Showing the first eight; more decompositions exist.
