Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646766, here are decompositions:

47 + 8646719 = 8646766
59 + 8646707 = 8646766
83 + 8646683 = 8646766
263 + 8646503 = 8646766
269 + 8646497 = 8646766
389 + 8646377 = 8646766
449 + 8646317 = 8646766
467 + 8646299 = 8646766

Showing the first eight; more decompositions exist.
