Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718566, here are decompositions:

79 + 8718487 = 8718566
97 + 8718469 = 8718566
127 + 8718439 = 8718566
139 + 8718427 = 8718566
223 + 8718343 = 8718566
349 + 8718217 = 8718566
457 + 8718109 = 8718566
463 + 8718103 = 8718566

Showing the first eight; more decompositions exist.
