Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487930, here are decompositions:

17 + 33487913 = 33487930
23 + 33487907 = 33487930
29 + 33487901 = 33487930
53 + 33487877 = 33487930
71 + 33487859 = 33487930
83 + 33487847 = 33487930
173 + 33487757 = 33487930
197 + 33487733 = 33487930

Showing the first eight; more decompositions exist.
