Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646886, here are decompositions:

107 + 8646779 = 8646886
167 + 8646719 = 8646886
179 + 8646707 = 8646886
383 + 8646503 = 8646886
389 + 8646497 = 8646886
509 + 8646377 = 8646886
557 + 8646329 = 8646886
569 + 8646317 = 8646886

Showing the first eight; more decompositions exist.
