Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661536, here are decompositions:

7 + 8661529 = 8661536
67 + 8661469 = 8661536
97 + 8661439 = 8661536
109 + 8661427 = 8661536
283 + 8661253 = 8661536
313 + 8661223 = 8661536
487 + 8661049 = 8661536
607 + 8660929 = 8661536

Showing the first eight; more decompositions exist.
