Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718270, here are decompositions:

19 + 8718251 = 8718270
23 + 8718247 = 8718270
53 + 8718217 = 8718270
73 + 8718197 = 8718270
79 + 8718191 = 8718270
107 + 8718163 = 8718270
157 + 8718113 = 8718270
167 + 8718103 = 8718270

Showing the first eight; more decompositions exist.
