Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738450, here are decompositions:

3 + 8738447 = 8738450
13 + 8738437 = 8738450
43 + 8738407 = 8738450
67 + 8738383 = 8738450
73 + 8738377 = 8738450
151 + 8738299 = 8738450
157 + 8738293 = 8738450
211 + 8738239 = 8738450

Showing the first eight; more decompositions exist.
