Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 961290, here are decompositions:

7 + 961283 = 961290
13 + 961277 = 961290
17 + 961273 = 961290
47 + 961243 = 961290
89 + 961201 = 961290
101 + 961189 = 961290
103 + 961187 = 961290
107 + 961183 = 961290

Showing the first eight; more decompositions exist.
