Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491412, here are decompositions:

41 + 33491371 = 33491412
43 + 33491369 = 33491412
79 + 33491333 = 33491412
109 + 33491303 = 33491412
151 + 33491261 = 33491412
179 + 33491233 = 33491412
191 + 33491221 = 33491412
263 + 33491149 = 33491412

Showing the first eight; more decompositions exist.
