Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 940420, here are decompositions:

17 + 940403 = 940420
59 + 940361 = 940420
71 + 940349 = 940420
101 + 940319 = 940420
149 + 940271 = 940420
179 + 940241 = 940420
191 + 940229 = 940420
197 + 940223 = 940420

Showing the first eight; more decompositions exist.
