Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33572538, here are decompositions:

5 + 33572533 = 33572538
11 + 33572527 = 33572538
17 + 33572521 = 33572538
157 + 33572381 = 33572538
191 + 33572347 = 33572538
199 + 33572339 = 33572538
227 + 33572311 = 33572538
229 + 33572309 = 33572538

Showing the first eight; more decompositions exist.
