Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491164, here are decompositions:

11 + 33491153 = 33491164
17 + 33491147 = 33491164
23 + 33491141 = 33491164
53 + 33491111 = 33491164
101 + 33491063 = 33491164
107 + 33491057 = 33491164
167 + 33490997 = 33491164
173 + 33490991 = 33491164

Showing the first eight; more decompositions exist.
