Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715572, here are decompositions:

13 + 8715559 = 8715572
163 + 8715409 = 8715572
211 + 8715361 = 8715572
223 + 8715349 = 8715572
379 + 8715193 = 8715572
421 + 8715151 = 8715572
631 + 8714941 = 8715572
751 + 8714821 = 8715572

Showing the first eight; more decompositions exist.
