Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33538388, here are decompositions:

61 + 33538327 = 33538388
67 + 33538321 = 33538388
157 + 33538231 = 33538388
181 + 33538207 = 33538388
229 + 33538159 = 33538388
307 + 33538081 = 33538388
337 + 33538051 = 33538388
379 + 33538009 = 33538388

Showing the first eight; more decompositions exist.
