Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33518398, here are decompositions:

5 + 33518393 = 33518398
47 + 33518351 = 33518398
71 + 33518327 = 33518398
101 + 33518297 = 33518398
131 + 33518267 = 33518398
257 + 33518141 = 33518398
317 + 33518081 = 33518398
491 + 33517907 = 33518398

Showing the first eight; more decompositions exist.
