Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521520, here are decompositions:

37 + 33521483 = 33521520
59 + 33521461 = 33521520
83 + 33521437 = 33521520
89 + 33521431 = 33521520
103 + 33521417 = 33521520
127 + 33521393 = 33521520
199 + 33521321 = 33521520
283 + 33521237 = 33521520

Showing the first eight; more decompositions exist.
