Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645836, here are decompositions:

47 + 8645789 = 8645836
107 + 8645729 = 8645836
149 + 8645687 = 8645836
167 + 8645669 = 8645836
179 + 8645657 = 8645836
239 + 8645597 = 8645836
257 + 8645579 = 8645836
293 + 8645543 = 8645836

Showing the first eight; more decompositions exist.
