Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491418, here are decompositions:

31 + 33491387 = 33491418
47 + 33491371 = 33491418
151 + 33491267 = 33491418
157 + 33491261 = 33491418
197 + 33491221 = 33491418
269 + 33491149 = 33491418
271 + 33491147 = 33491418
277 + 33491141 = 33491418

Showing the first eight; more decompositions exist.
