Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123402, here are decompositions:

5 + 123397 = 123402
23 + 123379 = 123402
29 + 123373 = 123402
61 + 123341 = 123402
79 + 123323 = 123402
113 + 123289 = 123402
163 + 123239 = 123402
173 + 123229 = 123402

Showing the first eight; more decompositions exist.
