Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123404, here are decompositions:

3 + 123401 = 123404
7 + 123397 = 123404
31 + 123373 = 123404
97 + 123307 = 123404
277 + 123127 = 123404
283 + 123121 = 123404
313 + 123091 = 123404
373 + 123031 = 123404

Showing the first eight; more decompositions exist.
