Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 940870, here are decompositions:

17 + 940853 = 940870
41 + 940829 = 940870
53 + 940817 = 940870
83 + 940787 = 940870
89 + 940781 = 940870
131 + 940739 = 940870
137 + 940733 = 940870
149 + 940721 = 940870

Showing the first eight; more decompositions exist.
