Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9438, here are decompositions:

5 + 9433 = 9438
7 + 9431 = 9438
17 + 9421 = 9438
19 + 9419 = 9438
41 + 9397 = 9438
47 + 9391 = 9438
61 + 9377 = 9438
67 + 9371 = 9438

Showing the first eight; more decompositions exist.
