Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33493978, here are decompositions:

5 + 33493973 = 33493978
71 + 33493907 = 33493978
101 + 33493877 = 33493978
107 + 33493871 = 33493978
137 + 33493841 = 33493978
149 + 33493829 = 33493978
359 + 33493619 = 33493978
449 + 33493529 = 33493978

Showing the first eight; more decompositions exist.
