Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33571138, here are decompositions:

5 + 33571133 = 33571138
17 + 33571121 = 33571138
47 + 33571091 = 33571138
59 + 33571079 = 33571138
89 + 33571049 = 33571138
101 + 33571037 = 33571138
239 + 33570899 = 33571138
257 + 33570881 = 33571138

Showing the first eight; more decompositions exist.
