Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 961578, here are decompositions:

11 + 961567 = 961578
29 + 961549 = 961578
31 + 961547 = 961578
47 + 961531 = 961578
67 + 961511 = 961578
71 + 961507 = 961578
127 + 961451 = 961578
131 + 961447 = 961578

Showing the first eight; more decompositions exist.
