Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491268, here are decompositions:

7 + 33491261 = 33491268
47 + 33491221 = 33491268
127 + 33491141 = 33491268
157 + 33491111 = 33491268
211 + 33491057 = 33491268
227 + 33491041 = 33491268
269 + 33490999 = 33491268
271 + 33490997 = 33491268

Showing the first eight; more decompositions exist.
