Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 940538, here are decompositions:

7 + 940531 = 940538
37 + 940501 = 940538
61 + 940477 = 940538
139 + 940399 = 940538
211 + 940327 = 940538
241 + 940297 = 940538
337 + 940201 = 940538
349 + 940189 = 940538

Showing the first eight; more decompositions exist.
