Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123542, here are decompositions:

43 + 123499 = 123542
103 + 123439 = 123542
109 + 123433 = 123542
163 + 123379 = 123542
283 + 123259 = 123542
313 + 123229 = 123542
373 + 123169 = 123542
421 + 123121 = 123542

Showing the first eight; more decompositions exist.
