Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715130, here are decompositions:

23 + 8715107 = 8715130
71 + 8715059 = 8715130
89 + 8715041 = 8715130
101 + 8715029 = 8715130
107 + 8715023 = 8715130
167 + 8714963 = 8715130
173 + 8714957 = 8715130
227 + 8714903 = 8715130

Showing the first eight; more decompositions exist.
