Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718172, here are decompositions:

59 + 8718113 = 8718172
83 + 8718089 = 8718172
173 + 8717999 = 8718172
179 + 8717993 = 8718172
191 + 8717981 = 8718172
233 + 8717939 = 8718172
263 + 8717909 = 8718172
311 + 8717861 = 8718172

Showing the first eight; more decompositions exist.
