Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33511440, here are decompositions:

31 + 33511409 = 33511440
41 + 33511399 = 33511440
43 + 33511397 = 33511440
73 + 33511367 = 33511440
101 + 33511339 = 33511440
103 + 33511337 = 33511440
163 + 33511277 = 33511440
191 + 33511249 = 33511440

Showing the first eight; more decompositions exist.
