Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718564, here are decompositions:

61 + 8718503 = 8718564
73 + 8718491 = 8718564
103 + 8718461 = 8718564
137 + 8718427 = 8718564
157 + 8718407 = 8718564
163 + 8718401 = 8718564
251 + 8718313 = 8718564
263 + 8718301 = 8718564

Showing the first eight; more decompositions exist.
