Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636994, here are decompositions:

5 + 8636989 = 8636994
7 + 8636987 = 8636994
71 + 8636923 = 8636994
73 + 8636921 = 8636994
83 + 8636911 = 8636994
101 + 8636893 = 8636994
137 + 8636857 = 8636994
193 + 8636801 = 8636994

Showing the first eight; more decompositions exist.
