Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718162, here are decompositions:

53 + 8718109 = 8718162
59 + 8718103 = 8718162
71 + 8718091 = 8718162
73 + 8718089 = 8718162
149 + 8718013 = 8718162
151 + 8718011 = 8718162
163 + 8717999 = 8718162
181 + 8717981 = 8718162

Showing the first eight; more decompositions exist.
