Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 961560, here are decompositions:

11 + 961549 = 961560
13 + 961547 = 961560
29 + 961531 = 961560
31 + 961529 = 961560
53 + 961507 = 961560
73 + 961487 = 961560
101 + 961459 = 961560
107 + 961453 = 961560

Showing the first eight; more decompositions exist.
