Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 961156, here are decompositions:

5 + 961151 = 961156
17 + 961139 = 961156
23 + 961133 = 961156
47 + 961109 = 961156
59 + 961097 = 961156
83 + 961073 = 961156
89 + 961067 = 961156
167 + 960989 = 961156

Showing the first eight; more decompositions exist.
