Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 961138, here are decompositions:

5 + 961133 = 961138
29 + 961109 = 961138
41 + 961097 = 961138
47 + 961091 = 961138
71 + 961067 = 961138
149 + 960989 = 961138
197 + 960941 = 961138
401 + 960737 = 961138

Showing the first eight; more decompositions exist.
