Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715942, here are decompositions:

5 + 8715937 = 8715942
41 + 8715901 = 8715942
61 + 8715881 = 8715942
101 + 8715841 = 8715942
149 + 8715793 = 8715942
163 + 8715779 = 8715942
173 + 8715769 = 8715942
181 + 8715761 = 8715942

Showing the first eight; more decompositions exist.
