Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521878, here are decompositions:

17 + 33521861 = 33521878
149 + 33521729 = 33521878
167 + 33521711 = 33521878
347 + 33521531 = 33521878
461 + 33521417 = 33521878
557 + 33521321 = 33521878
641 + 33521237 = 33521878
659 + 33521219 = 33521878

Showing the first eight; more decompositions exist.
