Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 940830, here are decompositions:

13 + 940817 = 940830
17 + 940813 = 940830
29 + 940801 = 940830
43 + 940787 = 940830
47 + 940783 = 940830
71 + 940759 = 940830
97 + 940733 = 940830
103 + 940727 = 940830

Showing the first eight; more decompositions exist.
