Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 961940, here are decompositions:

3 + 961937 = 961940
13 + 961927 = 961940
61 + 961879 = 961940
79 + 961861 = 961940
127 + 961813 = 961940
151 + 961789 = 961940
157 + 961783 = 961940
163 + 961777 = 961940

Showing the first eight; more decompositions exist.
