Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718164, here are decompositions:

61 + 8718103 = 8718164
67 + 8718097 = 8718164
73 + 8718091 = 8718164
151 + 8718013 = 8718164
157 + 8718007 = 8718164
283 + 8717881 = 8718164
307 + 8717857 = 8718164
373 + 8717791 = 8718164

Showing the first eight; more decompositions exist.
