Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715120, here are decompositions:

13 + 8715107 = 8715120
17 + 8715103 = 8715120
41 + 8715079 = 8715120
61 + 8715059 = 8715120
79 + 8715041 = 8715120
97 + 8715023 = 8715120
101 + 8715019 = 8715120
107 + 8715013 = 8715120

Showing the first eight; more decompositions exist.
