Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640198, here are decompositions:

11 + 8640187 = 8640198
29 + 8640169 = 8640198
37 + 8640161 = 8640198
89 + 8640109 = 8640198
139 + 8640059 = 8640198
181 + 8640017 = 8640198
197 + 8640001 = 8640198
211 + 8639987 = 8640198

Showing the first eight; more decompositions exist.
