Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9426, here are decompositions:

5 + 9421 = 9426
7 + 9419 = 9426
13 + 9413 = 9426
23 + 9403 = 9426
29 + 9397 = 9426
83 + 9343 = 9426
89 + 9337 = 9426
103 + 9323 = 9426

Showing the first eight; more decompositions exist.
