Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33518878, here are decompositions:

5 + 33518873 = 33518878
17 + 33518861 = 33518878
59 + 33518819 = 33518878
227 + 33518651 = 33518878
257 + 33518621 = 33518878
269 + 33518609 = 33518878
461 + 33518417 = 33518878
797 + 33518081 = 33518878

Showing the first eight; more decompositions exist.
