Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9378, here are decompositions:

7 + 9371 = 9378
29 + 9349 = 9378
37 + 9341 = 9378
41 + 9337 = 9378
59 + 9319 = 9378
67 + 9311 = 9378
97 + 9281 = 9378
101 + 9277 = 9378

Showing the first eight; more decompositions exist.
