Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670668, here are decompositions:

31 + 8670637 = 8670668
79 + 8670589 = 8670668
109 + 8670559 = 8670668
271 + 8670397 = 8670668
337 + 8670331 = 8670668
367 + 8670301 = 8670668
541 + 8670127 = 8670668
631 + 8670037 = 8670668

Showing the first eight; more decompositions exist.
