Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718138, here are decompositions:

29 + 8718109 = 8718138
41 + 8718097 = 8718138
47 + 8718091 = 8718138
127 + 8718011 = 8718138
131 + 8718007 = 8718138
139 + 8717999 = 8718138
151 + 8717987 = 8718138
157 + 8717981 = 8718138

Showing the first eight; more decompositions exist.
