Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718020, here are decompositions:

7 + 8718013 = 8718020
13 + 8718007 = 8718020
61 + 8717959 = 8718020
139 + 8717881 = 8718020
151 + 8717869 = 8718020
163 + 8717857 = 8718020
211 + 8717809 = 8718020
229 + 8717791 = 8718020

Showing the first eight; more decompositions exist.
