Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123388, here are decompositions:

11 + 123377 = 123388
47 + 123341 = 123388
149 + 123239 = 123388
179 + 123209 = 123388
197 + 123191 = 123388
311 + 123077 = 123388
431 + 122957 = 123388
449 + 122939 = 123388

Showing the first eight; more decompositions exist.
