Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 961566, here are decompositions:

17 + 961549 = 961566
19 + 961547 = 961566
37 + 961529 = 961566
59 + 961507 = 961566
79 + 961487 = 961566
107 + 961459 = 961566
113 + 961453 = 961566
139 + 961427 = 961566

Showing the first eight; more decompositions exist.
