Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33511290, here are decompositions:

13 + 33511277 = 33511290
41 + 33511249 = 33511290
53 + 33511237 = 33511290
61 + 33511229 = 33511290
139 + 33511151 = 33511290
151 + 33511139 = 33511290
157 + 33511133 = 33511290
191 + 33511099 = 33511290

Showing the first eight; more decompositions exist.
