Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661696, here are decompositions:

7 + 8661689 = 8661696
13 + 8661683 = 8661696
23 + 8661673 = 8661696
53 + 8661643 = 8661696
67 + 8661629 = 8661696
73 + 8661623 = 8661696
139 + 8661557 = 8661696
167 + 8661529 = 8661696

Showing the first eight; more decompositions exist.
