Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491394, here are decompositions:

7 + 33491387 = 33491394
23 + 33491371 = 33491394
31 + 33491363 = 33491394
61 + 33491333 = 33491394
127 + 33491267 = 33491394
173 + 33491221 = 33491394
191 + 33491203 = 33491394
241 + 33491153 = 33491394

Showing the first eight; more decompositions exist.
