Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33571390, here are decompositions:

3 + 33571387 = 33571390
23 + 33571367 = 33571390
137 + 33571253 = 33571390
179 + 33571211 = 33571390
227 + 33571163 = 33571390
239 + 33571151 = 33571390
257 + 33571133 = 33571390
269 + 33571121 = 33571390

Showing the first eight; more decompositions exist.
