Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715018, here are decompositions:

5 + 8715013 = 8715018
7 + 8715011 = 8715018
29 + 8714989 = 8715018
61 + 8714957 = 8715018
71 + 8714947 = 8715018
97 + 8714921 = 8715018
197 + 8714821 = 8715018
229 + 8714789 = 8715018

Showing the first eight; more decompositions exist.
