Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33542042, here are decompositions:

19 + 33542023 = 33542042
103 + 33541939 = 33542042
109 + 33541933 = 33542042
181 + 33541861 = 33542042
223 + 33541819 = 33542042
241 + 33541801 = 33542042
271 + 33541771 = 33542042
349 + 33541693 = 33542042

Showing the first eight; more decompositions exist.
