Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33542540, here are decompositions:

139 + 33542401 = 33542540
151 + 33542389 = 33542540
181 + 33542359 = 33542540
277 + 33542263 = 33542540
307 + 33542233 = 33542540
313 + 33542227 = 33542540
349 + 33542191 = 33542540
373 + 33542167 = 33542540

Showing the first eight; more decompositions exist.
