Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487884, here are decompositions:

7 + 33487877 = 33487884
37 + 33487847 = 33487884
71 + 33487813 = 33487884
113 + 33487771 = 33487884
127 + 33487757 = 33487884
151 + 33487733 = 33487884
167 + 33487717 = 33487884
233 + 33487651 = 33487884

Showing the first eight; more decompositions exist.
