Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661732, here are decompositions:

5 + 8661727 = 8661732
29 + 8661703 = 8661732
43 + 8661689 = 8661732
59 + 8661673 = 8661732
89 + 8661643 = 8661732
103 + 8661629 = 8661732
109 + 8661623 = 8661732
151 + 8661581 = 8661732

Showing the first eight; more decompositions exist.
