Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487828, here are decompositions:

71 + 33487757 = 33487828
197 + 33487631 = 33487828
317 + 33487511 = 33487828
509 + 33487319 = 33487828
557 + 33487271 = 33487828
641 + 33487187 = 33487828
677 + 33487151 = 33487828
797 + 33487031 = 33487828

Showing the first eight; more decompositions exist.
