Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123340, here are decompositions:

17 + 123323 = 123340
29 + 123311 = 123340
71 + 123269 = 123340
101 + 123239 = 123340
131 + 123209 = 123340
137 + 123203 = 123340
149 + 123191 = 123340
197 + 123143 = 123340

Showing the first eight; more decompositions exist.
