Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9490, here are decompositions:

11 + 9479 = 9490
17 + 9473 = 9490
23 + 9467 = 9490
29 + 9461 = 9490
53 + 9437 = 9490
59 + 9431 = 9490
71 + 9419 = 9490
113 + 9377 = 9490

Showing the first eight; more decompositions exist.
