Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645164, here are decompositions:

23 + 8645141 = 8645164
41 + 8645123 = 8645164
83 + 8645081 = 8645164
173 + 8644991 = 8645164
251 + 8644913 = 8645164
383 + 8644781 = 8645164
461 + 8644703 = 8645164
503 + 8644661 = 8645164

Showing the first eight; more decompositions exist.
