Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491878, here are decompositions:

29 + 33491849 = 33491878
41 + 33491837 = 33491878
47 + 33491831 = 33491878
131 + 33491747 = 33491878
137 + 33491741 = 33491878
149 + 33491729 = 33491878
197 + 33491681 = 33491878
239 + 33491639 = 33491878

Showing the first eight; more decompositions exist.
