Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646998, here are decompositions:

37 + 8646961 = 8646998
109 + 8646889 = 8646998
181 + 8646817 = 8646998
277 + 8646721 = 8646998
331 + 8646667 = 8646998
439 + 8646559 = 8646998
487 + 8646511 = 8646998
541 + 8646457 = 8646998

Showing the first eight; more decompositions exist.
