Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668864, here are decompositions:

47 + 8668817 = 8668864
101 + 8668763 = 8668864
167 + 8668697 = 8668864
227 + 8668637 = 8668864
251 + 8668613 = 8668864
293 + 8668571 = 8668864
311 + 8668553 = 8668864
317 + 8668547 = 8668864

Showing the first eight; more decompositions exist.
