Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646398, here are decompositions:

37 + 8646361 = 8646398
139 + 8646259 = 8646398
151 + 8646247 = 8646398
337 + 8646061 = 8646398
457 + 8645941 = 8646398
499 + 8645899 = 8646398
751 + 8645647 = 8646398
811 + 8645587 = 8646398

Showing the first eight; more decompositions exist.
