Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 940638, here are decompositions:

19 + 940619 = 940638
31 + 940607 = 940638
89 + 940549 = 940638
107 + 940531 = 940638
109 + 940529 = 940638
137 + 940501 = 940638
239 + 940399 = 940638
269 + 940369 = 940638

Showing the first eight; more decompositions exist.
