Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33541978, here are decompositions:

47 + 33541931 = 33541978
59 + 33541919 = 33541978
149 + 33541829 = 33541978
269 + 33541709 = 33541978
311 + 33541667 = 33541978
359 + 33541619 = 33541978
401 + 33541577 = 33541978
521 + 33541457 = 33541978

Showing the first eight; more decompositions exist.
