Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 940540, here are decompositions:

11 + 940529 = 940540
17 + 940523 = 940540
71 + 940469 = 940540
137 + 940403 = 940540
179 + 940361 = 940540
191 + 940349 = 940540
239 + 940301 = 940540
269 + 940271 = 940540

Showing the first eight; more decompositions exist.
