Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521412, here are decompositions:

11 + 33521401 = 33521412
19 + 33521393 = 33521412
191 + 33521221 = 33521412
193 + 33521219 = 33521412
233 + 33521179 = 33521412
241 + 33521171 = 33521412
271 + 33521141 = 33521412
313 + 33521099 = 33521412

Showing the first eight; more decompositions exist.
