Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33542288, here are decompositions:

37 + 33542251 = 33542288
61 + 33542227 = 33542288
97 + 33542191 = 33542288
151 + 33542137 = 33542288
211 + 33542077 = 33542288
331 + 33541957 = 33542288
349 + 33541939 = 33542288
379 + 33541909 = 33542288

Showing the first eight; more decompositions exist.
