Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33542180, here are decompositions:

13 + 33542167 = 33542180
43 + 33542137 = 33542180
79 + 33542101 = 33542180
103 + 33542077 = 33542180
157 + 33542023 = 33542180
193 + 33541987 = 33542180
223 + 33541957 = 33542180
241 + 33541939 = 33542180

Showing the first eight; more decompositions exist.
