Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 961556, here are decompositions:

7 + 961549 = 961556
97 + 961459 = 961556
103 + 961453 = 961556
109 + 961447 = 961556
157 + 961399 = 961556
163 + 961393 = 961556
283 + 961273 = 961556
313 + 961243 = 961556

Showing the first eight; more decompositions exist.
