Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661716, here are decompositions:

13 + 8661703 = 8661716
43 + 8661673 = 8661716
73 + 8661643 = 8661716
139 + 8661577 = 8661716
163 + 8661553 = 8661716
229 + 8661487 = 8661716
277 + 8661439 = 8661716
463 + 8661253 = 8661716

Showing the first eight; more decompositions exist.
