Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8699784, here are decompositions:

13 + 8699771 = 8699784
31 + 8699753 = 8699784
53 + 8699731 = 8699784
61 + 8699723 = 8699784
151 + 8699633 = 8699784
173 + 8699611 = 8699784
211 + 8699573 = 8699784
227 + 8699557 = 8699784

Showing the first eight; more decompositions exist.
