Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491278, here are decompositions:

11 + 33491267 = 33491278
17 + 33491261 = 33491278
131 + 33491147 = 33491278
137 + 33491141 = 33491278
167 + 33491111 = 33491278
179 + 33491099 = 33491278
281 + 33490997 = 33491278
389 + 33490889 = 33491278

Showing the first eight; more decompositions exist.
