Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38340, here are decompositions:

7 + 38333 = 38340
11 + 38329 = 38340
13 + 38327 = 38340
19 + 38321 = 38340
23 + 38317 = 38340
37 + 38303 = 38340
41 + 38299 = 38340
53 + 38287 = 38340

Showing the first eight; more decompositions exist.
