Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644546, here are decompositions:

17 + 8644529 = 8644546
47 + 8644499 = 8644546
89 + 8644457 = 8644546
107 + 8644439 = 8644546
149 + 8644397 = 8644546
293 + 8644253 = 8644546
359 + 8644187 = 8644546
389 + 8644157 = 8644546

Showing the first eight; more decompositions exist.
