Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661534, here are decompositions:

5 + 8661529 = 8661534
43 + 8661491 = 8661534
47 + 8661487 = 8661534
73 + 8661461 = 8661534
97 + 8661437 = 8661534
107 + 8661427 = 8661534
127 + 8661407 = 8661534
151 + 8661383 = 8661534

Showing the first eight; more decompositions exist.
