Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644846, here are decompositions:

3 + 8644843 = 8644846
47 + 8644799 = 8644846
167 + 8644679 = 8644846
239 + 8644607 = 8644846
293 + 8644553 = 8644846
317 + 8644529 = 8644846
347 + 8644499 = 8644846
389 + 8644457 = 8644846

Showing the first eight; more decompositions exist.
