Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657946, here are decompositions:

13 + 8657933 = 8657946
19 + 8657927 = 8657946
23 + 8657923 = 8657946
43 + 8657903 = 8657946
97 + 8657849 = 8657946
113 + 8657833 = 8657946
163 + 8657783 = 8657946
179 + 8657767 = 8657946

Showing the first eight; more decompositions exist.
