Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126942, here are decompositions:

19 + 126923 = 126942
29 + 126913 = 126942
83 + 126859 = 126942
103 + 126839 = 126942
181 + 126761 = 126942
191 + 126751 = 126942
199 + 126743 = 126942
223 + 126719 = 126942

Showing the first eight; more decompositions exist.
