Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123442, here are decompositions:

3 + 123439 = 123442
23 + 123419 = 123442
41 + 123401 = 123442
101 + 123341 = 123442
131 + 123311 = 123442
173 + 123269 = 123442
233 + 123209 = 123442
239 + 123203 = 123442

Showing the first eight; more decompositions exist.
