Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729164, here are decompositions:

23 + 8729141 = 8729164
47 + 8729117 = 8729164
71 + 8729093 = 8729164
83 + 8729081 = 8729164
107 + 8729057 = 8729164
113 + 8729051 = 8729164
131 + 8729033 = 8729164
263 + 8728901 = 8729164

Showing the first eight; more decompositions exist.
