Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718190, here are decompositions:

101 + 8718089 = 8718190
179 + 8718011 = 8718190
191 + 8717999 = 8718190
197 + 8717993 = 8718190
227 + 8717963 = 8718190
251 + 8717939 = 8718190
263 + 8717927 = 8718190
281 + 8717909 = 8718190

Showing the first eight; more decompositions exist.
