Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8654784, here are decompositions:

11 + 8654773 = 8654784
13 + 8654771 = 8654784
23 + 8654761 = 8654784
31 + 8654753 = 8654784
71 + 8654713 = 8654784
163 + 8654621 = 8654784
167 + 8654617 = 8654784
211 + 8654573 = 8654784

Showing the first eight; more decompositions exist.
