Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33572142, here are decompositions:

11 + 33572131 = 33572142
59 + 33572083 = 33572142
61 + 33572081 = 33572142
101 + 33572041 = 33572142
113 + 33572029 = 33572142
179 + 33571963 = 33572142
199 + 33571943 = 33572142
211 + 33571931 = 33572142

Showing the first eight; more decompositions exist.
