Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 940872, here are decompositions:

19 + 940853 = 940872
43 + 940829 = 940872
59 + 940813 = 940872
71 + 940801 = 940872
89 + 940783 = 940872
113 + 940759 = 940872
139 + 940733 = 940872
151 + 940721 = 940872

Showing the first eight; more decompositions exist.
