Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 961320, here are decompositions:

7 + 961313 = 961320
37 + 961283 = 961320
43 + 961277 = 961320
47 + 961273 = 961320
79 + 961241 = 961320
131 + 961189 = 961320
137 + 961183 = 961320
163 + 961157 = 961320

Showing the first eight; more decompositions exist.
