Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487950, here are decompositions:

37 + 33487913 = 33487950
43 + 33487907 = 33487950
47 + 33487903 = 33487950
73 + 33487877 = 33487950
103 + 33487847 = 33487950
131 + 33487819 = 33487950
137 + 33487813 = 33487950
179 + 33487771 = 33487950

Showing the first eight; more decompositions exist.
