Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491998, here are decompositions:

11 + 33491987 = 33491998
17 + 33491981 = 33491998
149 + 33491849 = 33491998
167 + 33491831 = 33491998
251 + 33491747 = 33491998
257 + 33491741 = 33491998
269 + 33491729 = 33491998
317 + 33491681 = 33491998

Showing the first eight; more decompositions exist.
