Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742966, here are decompositions:

47 + 8742919 = 8742966
79 + 8742887 = 8742966
109 + 8742857 = 8742966
149 + 8742817 = 8742966
179 + 8742787 = 8742966
227 + 8742739 = 8742966
277 + 8742689 = 8742966
293 + 8742673 = 8742966

Showing the first eight; more decompositions exist.
