Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636990, here are decompositions:

3 + 8636987 = 8636990
31 + 8636959 = 8636990
67 + 8636923 = 8636990
73 + 8636917 = 8636990
79 + 8636911 = 8636990
97 + 8636893 = 8636990
151 + 8636839 = 8636990
199 + 8636791 = 8636990

Showing the first eight; more decompositions exist.
