Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644864, here are decompositions:

3 + 8644861 = 8644864
83 + 8644781 = 8644864
113 + 8644751 = 8644864
257 + 8644607 = 8644864
311 + 8644553 = 8644864
353 + 8644511 = 8644864
467 + 8644397 = 8644864
563 + 8644301 = 8644864

Showing the first eight; more decompositions exist.
