Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8601966, here are decompositions:

5 + 8601961 = 8601966
19 + 8601947 = 8601966
29 + 8601937 = 8601966
59 + 8601907 = 8601966
83 + 8601883 = 8601966
89 + 8601877 = 8601966
97 + 8601869 = 8601966
193 + 8601773 = 8601966

Showing the first eight; more decompositions exist.
