Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644626, here are decompositions:

17 + 8644609 = 8644626
19 + 8644607 = 8644626
73 + 8644553 = 8644626
97 + 8644529 = 8644626
127 + 8644499 = 8644626
149 + 8644477 = 8644626
173 + 8644453 = 8644626
229 + 8644397 = 8644626

Showing the first eight; more decompositions exist.
