Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9420, here are decompositions:

7 + 9413 = 9420
17 + 9403 = 9420
23 + 9397 = 9420
29 + 9391 = 9420
43 + 9377 = 9420
71 + 9349 = 9420
79 + 9341 = 9420
83 + 9337 = 9420

Showing the first eight; more decompositions exist.
