Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33511478, here are decompositions:

31 + 33511447 = 33511478
79 + 33511399 = 33511478
139 + 33511339 = 33511478
157 + 33511321 = 33511478
181 + 33511297 = 33511478
229 + 33511249 = 33511478
241 + 33511237 = 33511478
307 + 33511171 = 33511478

Showing the first eight; more decompositions exist.
