Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700668, here are decompositions:

19 + 8700649 = 8700668
79 + 8700589 = 8700668
139 + 8700529 = 8700668
157 + 8700511 = 8700668
211 + 8700457 = 8700668
307 + 8700361 = 8700668
499 + 8700169 = 8700668
547 + 8700121 = 8700668

Showing the first eight; more decompositions exist.
