Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 961636, here are decompositions:

3 + 961633 = 961636
17 + 961619 = 961636
23 + 961613 = 961636
89 + 961547 = 961636
107 + 961529 = 961636
149 + 961487 = 961636
239 + 961397 = 961636
317 + 961319 = 961636

Showing the first eight; more decompositions exist.
