Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491248, here are decompositions:

101 + 33491147 = 33491248
107 + 33491141 = 33491248
137 + 33491111 = 33491248
149 + 33491099 = 33491248
191 + 33491057 = 33491248
251 + 33490997 = 33491248
257 + 33490991 = 33491248
359 + 33490889 = 33491248

Showing the first eight; more decompositions exist.
