Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670784, here are decompositions:

11 + 8670773 = 8670784
41 + 8670743 = 8670784
71 + 8670713 = 8670784
131 + 8670653 = 8670784
173 + 8670611 = 8670784
233 + 8670551 = 8670784
251 + 8670533 = 8670784
281 + 8670503 = 8670784

Showing the first eight; more decompositions exist.
