Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645476, here are decompositions:

149 + 8645327 = 8645476
233 + 8645243 = 8645476
239 + 8645237 = 8645476
353 + 8645123 = 8645476
467 + 8645009 = 8645476
557 + 8644919 = 8645476
563 + 8644913 = 8645476
677 + 8644799 = 8645476

Showing the first eight; more decompositions exist.
