Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33571240, here are decompositions:

29 + 33571211 = 33571240
89 + 33571151 = 33571240
107 + 33571133 = 33571240
137 + 33571103 = 33571240
149 + 33571091 = 33571240
191 + 33571049 = 33571240
359 + 33570881 = 33571240
389 + 33570851 = 33571240

Showing the first eight; more decompositions exist.
