Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645404, here are decompositions:

23 + 8645381 = 8645404
137 + 8645267 = 8645404
167 + 8645237 = 8645404
263 + 8645141 = 8645404
281 + 8645123 = 8645404
491 + 8644913 = 8645404
653 + 8644751 = 8645404
701 + 8644703 = 8645404

Showing the first eight; more decompositions exist.
