Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123676, here are decompositions:

23 + 123653 = 123676
83 + 123593 = 123676
149 + 123527 = 123676
173 + 123503 = 123676
197 + 123479 = 123676
227 + 123449 = 123676
257 + 123419 = 123676
269 + 123407 = 123676

Showing the first eight; more decompositions exist.
