Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636992, here are decompositions:

3 + 8636989 = 8636992
5 + 8636987 = 8636992
71 + 8636921 = 8636992
83 + 8636909 = 8636992
173 + 8636819 = 8636992
191 + 8636801 = 8636992
233 + 8636759 = 8636992
251 + 8636741 = 8636992

Showing the first eight; more decompositions exist.
