Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738444, here are decompositions:

7 + 8738437 = 8738444
37 + 8738407 = 8738444
61 + 8738383 = 8738444
67 + 8738377 = 8738444
151 + 8738293 = 8738444
163 + 8738281 = 8738444
181 + 8738263 = 8738444
283 + 8738161 = 8738444

Showing the first eight; more decompositions exist.
