Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 940490, here are decompositions:

7 + 940483 = 940490
13 + 940477 = 940490
139 + 940351 = 940490
163 + 940327 = 940490
193 + 940297 = 940490
211 + 940279 = 940490
241 + 940249 = 940490
307 + 940183 = 940490

Showing the first eight; more decompositions exist.
