Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636998, here are decompositions:

11 + 8636987 = 8636998
89 + 8636909 = 8636998
179 + 8636819 = 8636998
197 + 8636801 = 8636998
239 + 8636759 = 8636998
257 + 8636741 = 8636998
449 + 8636549 = 8636998
761 + 8636237 = 8636998

Showing the first eight; more decompositions exist.
