Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715930, here are decompositions:

23 + 8715907 = 8715930
29 + 8715901 = 8715930
43 + 8715887 = 8715930
53 + 8715877 = 8715930
89 + 8715841 = 8715930
137 + 8715793 = 8715930
151 + 8715779 = 8715930
199 + 8715731 = 8715930

Showing the first eight; more decompositions exist.
