Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33572146, here are decompositions:

5 + 33572141 = 33572146
29 + 33572117 = 33572146
137 + 33572009 = 33572146
149 + 33571997 = 33572146
317 + 33571829 = 33572146
353 + 33571793 = 33572146
659 + 33571487 = 33572146
683 + 33571463 = 33572146

Showing the first eight; more decompositions exist.
