Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668584, here are decompositions:

7 + 8668577 = 8668584
13 + 8668571 = 8668584
31 + 8668553 = 8668584
37 + 8668547 = 8668584
61 + 8668523 = 8668584
83 + 8668501 = 8668584
101 + 8668483 = 8668584
163 + 8668421 = 8668584

Showing the first eight; more decompositions exist.
