Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123320, here are decompositions:

13 + 123307 = 123320
31 + 123289 = 123320
61 + 123259 = 123320
103 + 123217 = 123320
151 + 123169 = 123320
193 + 123127 = 123320
199 + 123121 = 123320
229 + 123091 = 123320

Showing the first eight; more decompositions exist.
