Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729404, here are decompositions:

3 + 8729401 = 8729404
71 + 8729333 = 8729404
113 + 8729291 = 8729404
197 + 8729207 = 8729404
263 + 8729141 = 8729404
311 + 8729093 = 8729404
347 + 8729057 = 8729404
353 + 8729051 = 8729404

Showing the first eight; more decompositions exist.
