Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521668, here are decompositions:

137 + 33521531 = 33521668
197 + 33521471 = 33521668
251 + 33521417 = 33521668
347 + 33521321 = 33521668
431 + 33521237 = 33521668
449 + 33521219 = 33521668
491 + 33521177 = 33521668
569 + 33521099 = 33521668

Showing the first eight; more decompositions exist.
