Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646818, here are decompositions:

67 + 8646751 = 8646818
97 + 8646721 = 8646818
109 + 8646709 = 8646818
151 + 8646667 = 8646818
211 + 8646607 = 8646818
307 + 8646511 = 8646818
331 + 8646487 = 8646818
457 + 8646361 = 8646818

Showing the first eight; more decompositions exist.
