Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729082, here are decompositions:

23 + 8729059 = 8729082
29 + 8729053 = 8729082
31 + 8729051 = 8729082
113 + 8728969 = 8729082
139 + 8728943 = 8729082
179 + 8728903 = 8729082
181 + 8728901 = 8729082
199 + 8728883 = 8729082

Showing the first eight; more decompositions exist.
