Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33572128, here are decompositions:

11 + 33572117 = 33572128
47 + 33572081 = 33572128
101 + 33572027 = 33572128
131 + 33571997 = 33572128
197 + 33571931 = 33572128
311 + 33571817 = 33572128
389 + 33571739 = 33572128
419 + 33571709 = 33572128

Showing the first eight; more decompositions exist.
