Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6340, here are decompositions:

3 + 6337 = 6340
11 + 6329 = 6340
17 + 6323 = 6340
23 + 6317 = 6340
29 + 6311 = 6340
41 + 6299 = 6340
53 + 6287 = 6340
71 + 6269 = 6340

Showing the first eight; more decompositions exist.
