Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717572, here are decompositions:

41 + 8717531 = 8717572
179 + 8717393 = 8717572
359 + 8717213 = 8717572
401 + 8717171 = 8717572
449 + 8717123 = 8717572
653 + 8716919 = 8717572
683 + 8716889 = 8717572
719 + 8716853 = 8717572

Showing the first eight; more decompositions exist.
