Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729538, here are decompositions:

47 + 8729491 = 8729538
71 + 8729467 = 8729538
109 + 8729429 = 8729538
127 + 8729411 = 8729538
137 + 8729401 = 8729538
149 + 8729389 = 8729538
211 + 8729327 = 8729538
229 + 8729309 = 8729538

Showing the first eight; more decompositions exist.
