Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 961830, here are decompositions:

13 + 961817 = 961830
17 + 961813 = 961830
19 + 961811 = 961830
41 + 961789 = 961830
47 + 961783 = 961830
53 + 961777 = 961830
61 + 961769 = 961830
73 + 961757 = 961830

Showing the first eight; more decompositions exist.
