Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718120, here are decompositions:

7 + 8718113 = 8718120
11 + 8718109 = 8718120
17 + 8718103 = 8718120
23 + 8718097 = 8718120
29 + 8718091 = 8718120
31 + 8718089 = 8718120
107 + 8718013 = 8718120
109 + 8718011 = 8718120

Showing the first eight; more decompositions exist.
