Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661756, here are decompositions:

13 + 8661743 = 8661756
23 + 8661733 = 8661756
29 + 8661727 = 8661756
53 + 8661703 = 8661756
67 + 8661689 = 8661756
73 + 8661683 = 8661756
83 + 8661673 = 8661756
113 + 8661643 = 8661756

Showing the first eight; more decompositions exist.
