Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938644, here are decompositions:

53 + 938591 = 938644
71 + 938573 = 938644
107 + 938537 = 938644
137 + 938507 = 938644
191 + 938453 = 938644
197 + 938447 = 938644
251 + 938393 = 938644
257 + 938387 = 938644

Showing the first eight; more decompositions exist.
