Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521508, here are decompositions:

37 + 33521471 = 33521508
47 + 33521461 = 33521508
71 + 33521437 = 33521508
107 + 33521401 = 33521508
271 + 33521237 = 33521508
331 + 33521177 = 33521508
337 + 33521171 = 33521508
367 + 33521141 = 33521508

Showing the first eight; more decompositions exist.
