Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 940866, here are decompositions:

13 + 940853 = 940866
37 + 940829 = 940866
53 + 940813 = 940866
79 + 940787 = 940866
83 + 940783 = 940866
107 + 940759 = 940866
127 + 940739 = 940866
139 + 940727 = 940866

Showing the first eight; more decompositions exist.
