Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 961572, here are decompositions:

5 + 961567 = 961572
23 + 961549 = 961572
41 + 961531 = 961572
43 + 961529 = 961572
61 + 961511 = 961572
113 + 961459 = 961572
173 + 961399 = 961572
179 + 961393 = 961572

Showing the first eight; more decompositions exist.
