Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009784, here are decompositions:

3 + 1009781 = 1009784
37 + 1009747 = 1009784
43 + 1009741 = 1009784
157 + 1009627 = 1009784
163 + 1009621 = 1009784
211 + 1009573 = 1009784
277 + 1009507 = 1009784
283 + 1009501 = 1009784

Showing the first eight; more decompositions exist.
