Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661726, here are decompositions:

19 + 8661707 = 8661726
23 + 8661703 = 8661726
37 + 8661689 = 8661726
43 + 8661683 = 8661726
53 + 8661673 = 8661726
83 + 8661643 = 8661726
97 + 8661629 = 8661726
103 + 8661623 = 8661726

Showing the first eight; more decompositions exist.
