Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 940858, here are decompositions:

5 + 940853 = 940858
29 + 940829 = 940858
41 + 940817 = 940858
71 + 940787 = 940858
131 + 940727 = 940858
137 + 940721 = 940858
167 + 940691 = 940858
239 + 940619 = 940858

Showing the first eight; more decompositions exist.
