Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640708, here are decompositions:

5 + 8640703 = 8640708
7 + 8640701 = 8640708
17 + 8640691 = 8640708
19 + 8640689 = 8640708
29 + 8640679 = 8640708
107 + 8640601 = 8640708
149 + 8640559 = 8640708
227 + 8640481 = 8640708

Showing the first eight; more decompositions exist.
