Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487284, here are decompositions:

7 + 33487277 = 33487284
11 + 33487273 = 33487284
13 + 33487271 = 33487284
23 + 33487261 = 33487284
37 + 33487247 = 33487284
97 + 33487187 = 33487284
137 + 33487147 = 33487284
163 + 33487121 = 33487284

Showing the first eight; more decompositions exist.
