Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123574, here are decompositions:

23 + 123551 = 123574
47 + 123527 = 123574
71 + 123503 = 123574
83 + 123491 = 123574
167 + 123407 = 123574
173 + 123401 = 123574
197 + 123377 = 123574
233 + 123341 = 123574

Showing the first eight; more decompositions exist.
