Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33547986, here are decompositions:

5 + 33547981 = 33547986
13 + 33547973 = 33547986
29 + 33547957 = 33547986
97 + 33547889 = 33547986
113 + 33547873 = 33547986
137 + 33547849 = 33547986
139 + 33547847 = 33547986
223 + 33547763 = 33547986

Showing the first eight; more decompositions exist.
