Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123472, here are decompositions:

23 + 123449 = 123472
53 + 123419 = 123472
71 + 123401 = 123472
131 + 123341 = 123472
149 + 123323 = 123472
233 + 123239 = 123472
263 + 123209 = 123472
269 + 123203 = 123472

Showing the first eight; more decompositions exist.
