Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729784, here are decompositions:

17 + 8729767 = 8729784
67 + 8729717 = 8729784
73 + 8729711 = 8729784
103 + 8729681 = 8729784
137 + 8729647 = 8729784
163 + 8729621 = 8729784
181 + 8729603 = 8729784
191 + 8729593 = 8729784

Showing the first eight; more decompositions exist.
