Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33572168, here are decompositions:

37 + 33572131 = 33572168
127 + 33572041 = 33572168
139 + 33572029 = 33572168
229 + 33571939 = 33572168
337 + 33571831 = 33572168
349 + 33571819 = 33572168
367 + 33571801 = 33572168
499 + 33571669 = 33572168

Showing the first eight; more decompositions exist.
