Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189942, here are decompositions:

13 + 189929 = 189942
29 + 189913 = 189942
41 + 189901 = 189942
61 + 189881 = 189942
83 + 189859 = 189942
89 + 189853 = 189942
199 + 189743 = 189942
229 + 189713 = 189942

Showing the first eight; more decompositions exist.
