Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 961558, here are decompositions:

11 + 961547 = 961558
29 + 961529 = 961558
47 + 961511 = 961558
71 + 961487 = 961558
107 + 961451 = 961558
131 + 961427 = 961558
239 + 961319 = 961558
281 + 961277 = 961558

Showing the first eight; more decompositions exist.
