Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491872, here are decompositions:

23 + 33491849 = 33491872
41 + 33491831 = 33491872
131 + 33491741 = 33491872
179 + 33491693 = 33491872
191 + 33491681 = 33491872
233 + 33491639 = 33491872
251 + 33491621 = 33491872
269 + 33491603 = 33491872

Showing the first eight; more decompositions exist.
