Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729386, here are decompositions:

53 + 8729333 = 8729386
59 + 8729327 = 8729386
137 + 8729249 = 8729386
167 + 8729219 = 8729386
179 + 8729207 = 8729386
269 + 8729117 = 8729386
293 + 8729093 = 8729386
353 + 8729033 = 8729386

Showing the first eight; more decompositions exist.
