Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729402, here are decompositions:

13 + 8729389 = 8729402
79 + 8729323 = 8729402
163 + 8729239 = 8729402
181 + 8729221 = 8729402
211 + 8729191 = 8729402
223 + 8729179 = 8729402
229 + 8729173 = 8729402
271 + 8729131 = 8729402

Showing the first eight; more decompositions exist.
