Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33493540, here are decompositions:

11 + 33493529 = 33493540
149 + 33493391 = 33493540
167 + 33493373 = 33493540
233 + 33493307 = 33493540
257 + 33493283 = 33493540
317 + 33493223 = 33493540
383 + 33493157 = 33493540
401 + 33493139 = 33493540

Showing the first eight; more decompositions exist.
