Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33506578, here are decompositions:

5 + 33506573 = 33506578
29 + 33506549 = 33506578
101 + 33506477 = 33506578
179 + 33506399 = 33506578
191 + 33506387 = 33506578
257 + 33506321 = 33506578
269 + 33506309 = 33506578
311 + 33506267 = 33506578

Showing the first eight; more decompositions exist.
