Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636806, here are decompositions:

5 + 8636801 = 8636806
47 + 8636759 = 8636806
173 + 8636633 = 8636806
179 + 8636627 = 8636806
257 + 8636549 = 8636806
263 + 8636543 = 8636806
293 + 8636513 = 8636806
383 + 8636423 = 8636806

Showing the first eight; more decompositions exist.
