Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33511380, here are decompositions:

13 + 33511367 = 33511380
41 + 33511339 = 33511380
43 + 33511337 = 33511380
59 + 33511321 = 33511380
83 + 33511297 = 33511380
103 + 33511277 = 33511380
131 + 33511249 = 33511380
151 + 33511229 = 33511380

Showing the first eight; more decompositions exist.
