Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8330, here are decompositions:

13 + 8317 = 8330
19 + 8311 = 8330
37 + 8293 = 8330
43 + 8287 = 8330
61 + 8269 = 8330
67 + 8263 = 8330
97 + 8233 = 8330
109 + 8221 = 8330

Showing the first eight; more decompositions exist.
