Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8340, here are decompositions:

11 + 8329 = 8340
23 + 8317 = 8340
29 + 8311 = 8340
43 + 8297 = 8340
47 + 8293 = 8340
53 + 8287 = 8340
67 + 8273 = 8340
71 + 8269 = 8340

Showing the first eight; more decompositions exist.
