Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487866, here are decompositions:

7 + 33487859 = 33487866
19 + 33487847 = 33487866
47 + 33487819 = 33487866
53 + 33487813 = 33487866
107 + 33487759 = 33487866
109 + 33487757 = 33487866
149 + 33487717 = 33487866
227 + 33487639 = 33487866

Showing the first eight; more decompositions exist.
