Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491836, here are decompositions:

3 + 33491833 = 33491836
5 + 33491831 = 33491836
89 + 33491747 = 33491836
107 + 33491729 = 33491836
197 + 33491639 = 33491836
233 + 33491603 = 33491836
269 + 33491567 = 33491836
293 + 33491543 = 33491836

Showing the first eight; more decompositions exist.
