Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10320, here are decompositions:

7 + 10313 = 10320
17 + 10303 = 10320
19 + 10301 = 10320
31 + 10289 = 10320
47 + 10273 = 10320
53 + 10267 = 10320
61 + 10259 = 10320
67 + 10253 = 10320

Showing the first eight; more decompositions exist.
