Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 961770, here are decompositions:

13 + 961757 = 961770
23 + 961747 = 961770
31 + 961739 = 961770
37 + 961733 = 961770
41 + 961729 = 961770
67 + 961703 = 961770
79 + 961691 = 961770
83 + 961687 = 961770

Showing the first eight; more decompositions exist.
