Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33572138, here are decompositions:

7 + 33572131 = 33572138
97 + 33572041 = 33572138
109 + 33572029 = 33572138
199 + 33571939 = 33572138
307 + 33571831 = 33572138
331 + 33571807 = 33572138
337 + 33571801 = 33572138
499 + 33571639 = 33572138

Showing the first eight; more decompositions exist.
