Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 961980, here are decompositions:

7 + 961973 = 961980
23 + 961957 = 961980
37 + 961943 = 961980
43 + 961937 = 961980
53 + 961927 = 961980
101 + 961879 = 961980
109 + 961871 = 961980
127 + 961853 = 961980

Showing the first eight; more decompositions exist.
