Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 961540, here are decompositions:

11 + 961529 = 961540
29 + 961511 = 961540
53 + 961487 = 961540
89 + 961451 = 961540
113 + 961427 = 961540
227 + 961313 = 961540
257 + 961283 = 961540
263 + 961277 = 961540

Showing the first eight; more decompositions exist.
