Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491290, here are decompositions:

23 + 33491267 = 33491290
29 + 33491261 = 33491290
137 + 33491153 = 33491290
149 + 33491141 = 33491290
179 + 33491111 = 33491290
191 + 33491099 = 33491290
227 + 33491063 = 33491290
233 + 33491057 = 33491290

Showing the first eight; more decompositions exist.
