Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123538, here are decompositions:

11 + 123527 = 123538
47 + 123491 = 123538
59 + 123479 = 123538
89 + 123449 = 123538
131 + 123407 = 123538
137 + 123401 = 123538
197 + 123341 = 123538
227 + 123311 = 123538

Showing the first eight; more decompositions exist.
