Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729400, here are decompositions:

11 + 8729389 = 8729400
67 + 8729333 = 8729400
73 + 8729327 = 8729400
83 + 8729317 = 8729400
109 + 8729291 = 8729400
151 + 8729249 = 8729400
157 + 8729243 = 8729400
179 + 8729221 = 8729400

Showing the first eight; more decompositions exist.
