Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33572140, here are decompositions:

23 + 33572117 = 33572140
59 + 33572081 = 33572140
89 + 33572051 = 33572140
113 + 33572027 = 33572140
131 + 33572009 = 33572140
197 + 33571943 = 33572140
311 + 33571829 = 33572140
317 + 33571823 = 33572140

Showing the first eight; more decompositions exist.
