Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491986, here are decompositions:

5 + 33491981 = 33491986
137 + 33491849 = 33491986
149 + 33491837 = 33491986
239 + 33491747 = 33491986
257 + 33491729 = 33491986
293 + 33491693 = 33491986
347 + 33491639 = 33491986
383 + 33491603 = 33491986

Showing the first eight; more decompositions exist.
