Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747198, here are decompositions:

7 + 8747191 = 8747198
79 + 8747119 = 8747198
127 + 8747071 = 8747198
157 + 8747041 = 8747198
199 + 8746999 = 8747198
241 + 8746957 = 8747198
277 + 8746921 = 8747198
337 + 8746861 = 8747198

Showing the first eight; more decompositions exist.
