Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 961188, here are decompositions:

5 + 961183 = 961188
29 + 961159 = 961188
31 + 961157 = 961188
37 + 961151 = 961188
47 + 961141 = 961188
71 + 961117 = 961188
79 + 961109 = 961188
89 + 961099 = 961188

Showing the first eight; more decompositions exist.
