Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636878, here are decompositions:

59 + 8636819 = 8636878
137 + 8636741 = 8636878
251 + 8636627 = 8636878
491 + 8636387 = 8636878
617 + 8636261 = 8636878
641 + 8636237 = 8636878
659 + 8636219 = 8636878
797 + 8636081 = 8636878

Showing the first eight; more decompositions exist.
