Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645922, here are decompositions:

23 + 8645899 = 8645922
59 + 8645863 = 8645922
73 + 8645849 = 8645922
149 + 8645773 = 8645922
163 + 8645759 = 8645922
193 + 8645729 = 8645922
269 + 8645653 = 8645922
379 + 8645543 = 8645922

Showing the first eight; more decompositions exist.
