Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 961280, here are decompositions:

3 + 961277 = 961280
7 + 961273 = 961280
37 + 961243 = 961280
79 + 961201 = 961280
97 + 961183 = 961280
139 + 961141 = 961280
157 + 961123 = 961280
163 + 961117 = 961280

Showing the first eight; more decompositions exist.
