Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123392, here are decompositions:

13 + 123379 = 123392
19 + 123373 = 123392
103 + 123289 = 123392
163 + 123229 = 123392
223 + 123169 = 123392
271 + 123121 = 123392
421 + 122971 = 123392
439 + 122953 = 123392

Showing the first eight; more decompositions exist.
