Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33572520, here are decompositions:

17 + 33572503 = 33572520
31 + 33572489 = 33572520
73 + 33572447 = 33572520
103 + 33572417 = 33572520
139 + 33572381 = 33572520
167 + 33572353 = 33572520
173 + 33572347 = 33572520
181 + 33572339 = 33572520

Showing the first eight; more decompositions exist.
