Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729084, here are decompositions:

3 + 8729081 = 8729084
31 + 8729053 = 8729084
97 + 8728987 = 8729084
157 + 8728927 = 8729084
163 + 8728921 = 8729084
181 + 8728903 = 8729084
277 + 8728807 = 8729084
367 + 8728717 = 8729084

Showing the first eight; more decompositions exist.
