Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 940642, here are decompositions:

23 + 940619 = 940642
89 + 940553 = 940642
113 + 940529 = 940642
173 + 940469 = 940642
239 + 940403 = 940642
281 + 940361 = 940642
293 + 940349 = 940642
383 + 940259 = 940642

Showing the first eight; more decompositions exist.
