Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491388, here are decompositions:

17 + 33491371 = 33491388
19 + 33491369 = 33491388
127 + 33491261 = 33491388
167 + 33491221 = 33491388
239 + 33491149 = 33491388
241 + 33491147 = 33491388
277 + 33491111 = 33491388
331 + 33491057 = 33491388

Showing the first eight; more decompositions exist.
