Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644744, here are decompositions:

41 + 8644703 = 8644744
83 + 8644661 = 8644744
137 + 8644607 = 8644744
191 + 8644553 = 8644744
233 + 8644511 = 8644744
293 + 8644451 = 8644744
347 + 8644397 = 8644744
443 + 8644301 = 8644744

Showing the first eight; more decompositions exist.
