Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621198, here are decompositions:

97 + 8621101 = 8621198
109 + 8621089 = 8621198
151 + 8621047 = 8621198
181 + 8621017 = 8621198
337 + 8620861 = 8621198
577 + 8620621 = 8621198
631 + 8620567 = 8621198
769 + 8620429 = 8621198

Showing the first eight; more decompositions exist.
