Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641198, here are decompositions:

11 + 8641187 = 8641198
101 + 8641097 = 8641198
191 + 8641007 = 8641198
311 + 8640887 = 8641198
431 + 8640767 = 8641198
479 + 8640719 = 8641198
491 + 8640707 = 8641198
509 + 8640689 = 8641198

Showing the first eight; more decompositions exist.
