Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715020, here are decompositions:

7 + 8715013 = 8715020
31 + 8714989 = 8715020
37 + 8714983 = 8715020
73 + 8714947 = 8715020
79 + 8714941 = 8715020
163 + 8714857 = 8715020
199 + 8714821 = 8715020
241 + 8714779 = 8715020

Showing the first eight; more decompositions exist.
