Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715966, here are decompositions:

5 + 8715961 = 8715966
19 + 8715947 = 8715966
29 + 8715937 = 8715966
59 + 8715907 = 8715966
79 + 8715887 = 8715966
89 + 8715877 = 8715966
173 + 8715793 = 8715966
179 + 8715787 = 8715966

Showing the first eight; more decompositions exist.
