Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 961810, here are decompositions:

41 + 961769 = 961810
53 + 961757 = 961810
71 + 961739 = 961810
107 + 961703 = 961810
131 + 961679 = 961810
149 + 961661 = 961810
167 + 961643 = 961810
173 + 961637 = 961810

Showing the first eight; more decompositions exist.
