Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644474, here are decompositions:

17 + 8644457 = 8644474
23 + 8644451 = 8644474
173 + 8644301 = 8644474
317 + 8644157 = 8644474
383 + 8644091 = 8644474
521 + 8643953 = 8644474
653 + 8643821 = 8644474
677 + 8643797 = 8644474

Showing the first eight; more decompositions exist.
