Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33513478, here are decompositions:

71 + 33513407 = 33513478
197 + 33513281 = 33513478
281 + 33513197 = 33513478
311 + 33513167 = 33513478
491 + 33512987 = 33513478
641 + 33512837 = 33513478
797 + 33512681 = 33513478
941 + 33512537 = 33513478

Showing the first eight; more decompositions exist.
