Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646788, here are decompositions:

37 + 8646751 = 8646788
67 + 8646721 = 8646788
79 + 8646709 = 8646788
181 + 8646607 = 8646788
229 + 8646559 = 8646788
277 + 8646511 = 8646788
331 + 8646457 = 8646788
541 + 8646247 = 8646788

Showing the first eight; more decompositions exist.
