Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645198, here are decompositions:

19 + 8645179 = 8645198
127 + 8645071 = 8645198
151 + 8645047 = 8645198
241 + 8644957 = 8645198
271 + 8644927 = 8645198
337 + 8644861 = 8645198
547 + 8644651 = 8645198
691 + 8644507 = 8645198

Showing the first eight; more decompositions exist.
