Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 940390, here are decompositions:

29 + 940361 = 940390
41 + 940349 = 940390
71 + 940319 = 940390
89 + 940301 = 940390
131 + 940259 = 940390
149 + 940241 = 940390
167 + 940223 = 940390
233 + 940157 = 940390

Showing the first eight; more decompositions exist.
