Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 961128, here are decompositions:

5 + 961123 = 961128
11 + 961117 = 961128
19 + 961109 = 961128
29 + 961099 = 961128
31 + 961097 = 961128
37 + 961091 = 961128
41 + 961087 = 961128
59 + 961069 = 961128

Showing the first eight; more decompositions exist.
