Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668624, here are decompositions:

11 + 8668613 = 8668624
47 + 8668577 = 8668624
53 + 8668571 = 8668624
71 + 8668553 = 8668624
101 + 8668523 = 8668624
257 + 8668367 = 8668624
431 + 8668193 = 8668624
467 + 8668157 = 8668624

Showing the first eight; more decompositions exist.
