Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491428, here are decompositions:

11 + 33491417 = 33491428
41 + 33491387 = 33491428
59 + 33491369 = 33491428
167 + 33491261 = 33491428
281 + 33491147 = 33491428
317 + 33491111 = 33491428
431 + 33490997 = 33491428
479 + 33490949 = 33491428

Showing the first eight; more decompositions exist.
