Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644648, here are decompositions:

41 + 8644607 = 8644648
137 + 8644511 = 8644648
149 + 8644499 = 8644648
191 + 8644457 = 8644648
197 + 8644451 = 8644648
251 + 8644397 = 8644648
317 + 8644331 = 8644648
347 + 8644301 = 8644648

Showing the first eight; more decompositions exist.
