Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 940842, here are decompositions:

13 + 940829 = 940842
29 + 940813 = 940842
41 + 940801 = 940842
59 + 940783 = 940842
61 + 940781 = 940842
83 + 940759 = 940842
103 + 940739 = 940842
109 + 940733 = 940842

Showing the first eight; more decompositions exist.
