Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33542942, here are decompositions:

3 + 33542939 = 33542942
151 + 33542791 = 33542942
163 + 33542779 = 33542942
193 + 33542749 = 33542942
283 + 33542659 = 33542942
331 + 33542611 = 33542942
379 + 33542563 = 33542942
541 + 33542401 = 33542942

Showing the first eight; more decompositions exist.
