Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626784, here are decompositions:

7 + 8626777 = 8626784
37 + 8626747 = 8626784
163 + 8626621 = 8626784
181 + 8626603 = 8626784
277 + 8626507 = 8626784
367 + 8626417 = 8626784
487 + 8626297 = 8626784
541 + 8626243 = 8626784

Showing the first eight; more decompositions exist.
