Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 940388, here are decompositions:

19 + 940369 = 940388
37 + 940351 = 940388
61 + 940327 = 940388
109 + 940279 = 940388
139 + 940249 = 940388
199 + 940189 = 940388
457 + 939931 = 940388
487 + 939901 = 940388

Showing the first eight; more decompositions exist.
