Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491406, here are decompositions:

19 + 33491387 = 33491406
37 + 33491369 = 33491406
43 + 33491363 = 33491406
73 + 33491333 = 33491406
103 + 33491303 = 33491406
139 + 33491267 = 33491406
173 + 33491233 = 33491406
257 + 33491149 = 33491406

Showing the first eight; more decompositions exist.
