Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33511520, here are decompositions:

13 + 33511507 = 33511520
73 + 33511447 = 33511520
181 + 33511339 = 33511520
199 + 33511321 = 33511520
223 + 33511297 = 33511520
271 + 33511249 = 33511520
283 + 33511237 = 33511520
349 + 33511171 = 33511520

Showing the first eight; more decompositions exist.
