Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 961986, here are decompositions:

5 + 961981 = 961986
13 + 961973 = 961986
29 + 961957 = 961986
43 + 961943 = 961986
59 + 961927 = 961986
107 + 961879 = 961986
139 + 961847 = 961986
173 + 961813 = 961986

Showing the first eight; more decompositions exist.
