Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661588, here are decompositions:

7 + 8661581 = 8661588
11 + 8661577 = 8661588
17 + 8661571 = 8661588
31 + 8661557 = 8661588
59 + 8661529 = 8661588
79 + 8661509 = 8661588
97 + 8661491 = 8661588
101 + 8661487 = 8661588

Showing the first eight; more decompositions exist.
