Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521278, here are decompositions:

41 + 33521237 = 33521278
59 + 33521219 = 33521278
101 + 33521177 = 33521278
107 + 33521171 = 33521278
137 + 33521141 = 33521278
179 + 33521099 = 33521278
191 + 33521087 = 33521278
239 + 33521039 = 33521278

Showing the first eight; more decompositions exist.
