Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718286, here are decompositions:

89 + 8718197 = 8718286
173 + 8718113 = 8718286
197 + 8718089 = 8718286
293 + 8717993 = 8718286
347 + 8717939 = 8718286
359 + 8717927 = 8718286
419 + 8717867 = 8718286
443 + 8717843 = 8718286

Showing the first eight; more decompositions exist.
