Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491458, here are decompositions:

17 + 33491441 = 33491458
41 + 33491417 = 33491458
71 + 33491387 = 33491458
89 + 33491369 = 33491458
191 + 33491267 = 33491458
197 + 33491261 = 33491458
311 + 33491147 = 33491458
317 + 33491141 = 33491458

Showing the first eight; more decompositions exist.
