Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644784, here are decompositions:

3 + 8644781 = 8644784
13 + 8644771 = 8644784
61 + 8644723 = 8644784
151 + 8644633 = 8644784
277 + 8644507 = 8644784
283 + 8644501 = 8644784
307 + 8644477 = 8644784
331 + 8644453 = 8644784

Showing the first eight; more decompositions exist.
