Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8716572, here are decompositions:

5 + 8716567 = 8716572
19 + 8716553 = 8716572
41 + 8716531 = 8716572
83 + 8716489 = 8716572
103 + 8716469 = 8716572
131 + 8716441 = 8716572
191 + 8716381 = 8716572
199 + 8716373 = 8716572

Showing the first eight; more decompositions exist.
