Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123328, here are decompositions:

5 + 123323 = 123328
17 + 123311 = 123328
59 + 123269 = 123328
89 + 123239 = 123328
137 + 123191 = 123328
251 + 123077 = 123328
269 + 123059 = 123328
311 + 123017 = 123328

Showing the first eight; more decompositions exist.
