Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647028, here are decompositions:

7 + 8647021 = 8647028
67 + 8646961 = 8647028
79 + 8646949 = 8647028
139 + 8646889 = 8647028
211 + 8646817 = 8647028
277 + 8646751 = 8647028
307 + 8646721 = 8647028
421 + 8646607 = 8647028

Showing the first eight; more decompositions exist.
