Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644198, here are decompositions:

11 + 8644187 = 8644198
41 + 8644157 = 8644198
107 + 8644091 = 8644198
137 + 8644061 = 8644198
149 + 8644049 = 8644198
179 + 8644019 = 8644198
239 + 8643959 = 8644198
257 + 8643941 = 8644198

Showing the first eight; more decompositions exist.
