Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 961140, here are decompositions:

7 + 961133 = 961140
17 + 961123 = 961140
23 + 961117 = 961140
31 + 961109 = 961140
41 + 961099 = 961140
43 + 961097 = 961140
53 + 961087 = 961140
67 + 961073 = 961140

Showing the first eight; more decompositions exist.
