Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33478920, here are decompositions:

17 + 33478903 = 33478920
31 + 33478889 = 33478920
43 + 33478877 = 33478920
113 + 33478807 = 33478920
193 + 33478727 = 33478920
197 + 33478723 = 33478920
199 + 33478721 = 33478920
227 + 33478693 = 33478920

Showing the first eight; more decompositions exist.
