Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718522, here are decompositions:

19 + 8718503 = 8718522
31 + 8718491 = 8718522
53 + 8718469 = 8718522
61 + 8718461 = 8718522
83 + 8718439 = 8718522
103 + 8718419 = 8718522
173 + 8718349 = 8718522
179 + 8718343 = 8718522

Showing the first eight; more decompositions exist.
