Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33506740, here are decompositions:

167 + 33506573 = 33506740
191 + 33506549 = 33506740
263 + 33506477 = 33506740
347 + 33506393 = 33506740
353 + 33506387 = 33506740
419 + 33506321 = 33506740
431 + 33506309 = 33506740
479 + 33506261 = 33506740

Showing the first eight; more decompositions exist.
