Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33493578, here are decompositions:

5 + 33493573 = 33493578
11 + 33493567 = 33493578
29 + 33493549 = 33493578
37 + 33493541 = 33493578
191 + 33493387 = 33493578
257 + 33493321 = 33493578
269 + 33493309 = 33493578
271 + 33493307 = 33493578

Showing the first eight; more decompositions exist.
