Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123772, here are decompositions:

41 + 123731 = 123772
53 + 123719 = 123772
71 + 123701 = 123772
179 + 123593 = 123772
191 + 123581 = 123772
269 + 123503 = 123772
281 + 123491 = 123772
293 + 123479 = 123772

Showing the first eight; more decompositions exist.
