Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123700, here are decompositions:

23 + 123677 = 123700
47 + 123653 = 123700
107 + 123593 = 123700
149 + 123551 = 123700
173 + 123527 = 123700
197 + 123503 = 123700
251 + 123449 = 123700
281 + 123419 = 123700

Showing the first eight; more decompositions exist.
