Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521778, here are decompositions:

19 + 33521759 = 33521778
47 + 33521731 = 33521778
67 + 33521711 = 33521778
89 + 33521689 = 33521778
131 + 33521647 = 33521778
149 + 33521629 = 33521778
229 + 33521549 = 33521778
239 + 33521539 = 33521778

Showing the first eight; more decompositions exist.
