Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33538340, here are decompositions:

13 + 33538327 = 33538340
19 + 33538321 = 33538340
37 + 33538303 = 33538340
67 + 33538273 = 33538340
109 + 33538231 = 33538340
181 + 33538159 = 33538340
211 + 33538129 = 33538340
271 + 33538069 = 33538340

Showing the first eight; more decompositions exist.
