Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640064, here are decompositions:

5 + 8640059 = 8640064
47 + 8640017 = 8640064
113 + 8639951 = 8640064
227 + 8639837 = 8640064
311 + 8639753 = 8640064
317 + 8639747 = 8640064
353 + 8639711 = 8640064
401 + 8639663 = 8640064

Showing the first eight; more decompositions exist.
