Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636866, here are decompositions:

47 + 8636819 = 8636866
107 + 8636759 = 8636866
233 + 8636633 = 8636866
239 + 8636627 = 8636866
263 + 8636603 = 8636866
317 + 8636549 = 8636866
353 + 8636513 = 8636866
443 + 8636423 = 8636866

Showing the first eight; more decompositions exist.
