Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 961564, here are decompositions:

17 + 961547 = 961564
53 + 961511 = 961564
113 + 961451 = 961564
137 + 961427 = 961564
167 + 961397 = 961564
251 + 961313 = 961564
281 + 961283 = 961564
431 + 961133 = 961564

Showing the first eight; more decompositions exist.
