Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491154, here are decompositions:

5 + 33491149 = 33491154
7 + 33491147 = 33491154
13 + 33491141 = 33491154
43 + 33491111 = 33491154
97 + 33491057 = 33491154
113 + 33491041 = 33491154
157 + 33490997 = 33491154
163 + 33490991 = 33491154

Showing the first eight; more decompositions exist.
