Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661498, here are decompositions:

7 + 8661491 = 8661498
11 + 8661487 = 8661498
19 + 8661479 = 8661498
29 + 8661469 = 8661498
37 + 8661461 = 8661498
59 + 8661439 = 8661498
61 + 8661437 = 8661498
71 + 8661427 = 8661498

Showing the first eight; more decompositions exist.
