Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123646, here are decompositions:

53 + 123593 = 123646
167 + 123479 = 123646
197 + 123449 = 123646
227 + 123419 = 123646
239 + 123407 = 123646
269 + 123377 = 123646
443 + 123203 = 123646
503 + 123143 = 123646

Showing the first eight; more decompositions exist.
