Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521388, here are decompositions:

67 + 33521321 = 33521388
151 + 33521237 = 33521388
167 + 33521221 = 33521388
211 + 33521177 = 33521388
331 + 33521057 = 33521388
349 + 33521039 = 33521388
367 + 33521021 = 33521388
379 + 33521009 = 33521388

Showing the first eight; more decompositions exist.
