Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729412, here are decompositions:

11 + 8729401 = 8729412
23 + 8729389 = 8729412
79 + 8729333 = 8729412
89 + 8729323 = 8729412
103 + 8729309 = 8729412
163 + 8729249 = 8729412
173 + 8729239 = 8729412
191 + 8729221 = 8729412

Showing the first eight; more decompositions exist.
