Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33542028, here are decompositions:

5 + 33542023 = 33542028
31 + 33541997 = 33542028
41 + 33541987 = 33542028
71 + 33541957 = 33542028
89 + 33541939 = 33542028
97 + 33541931 = 33542028
109 + 33541919 = 33542028
167 + 33541861 = 33542028

Showing the first eight; more decompositions exist.
