Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8601816, here are decompositions:

43 + 8601773 = 8601816
73 + 8601743 = 8601816
89 + 8601727 = 8601816
109 + 8601707 = 8601816
127 + 8601689 = 8601816
149 + 8601667 = 8601816
163 + 8601653 = 8601816
229 + 8601587 = 8601816

Showing the first eight; more decompositions exist.
