Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33542978, here are decompositions:

127 + 33542851 = 33542978
151 + 33542827 = 33542978
199 + 33542779 = 33542978
229 + 33542749 = 33542978
241 + 33542737 = 33542978
367 + 33542611 = 33542978
421 + 33542557 = 33542978
439 + 33542539 = 33542978

Showing the first eight; more decompositions exist.
