Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 961180, here are decompositions:

23 + 961157 = 961180
29 + 961151 = 961180
41 + 961139 = 961180
47 + 961133 = 961180
71 + 961109 = 961180
83 + 961097 = 961180
89 + 961091 = 961180
107 + 961073 = 961180

Showing the first eight; more decompositions exist.
