Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123372, here are decompositions:

31 + 123341 = 123372
61 + 123311 = 123372
83 + 123289 = 123372
103 + 123269 = 123372
113 + 123259 = 123372
163 + 123209 = 123372
181 + 123191 = 123372
229 + 123143 = 123372

Showing the first eight; more decompositions exist.
