Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33518478, here are decompositions:

29 + 33518449 = 33518478
41 + 33518437 = 33518478
61 + 33518417 = 33518478
89 + 33518389 = 33518478
127 + 33518351 = 33518478
151 + 33518327 = 33518478
181 + 33518297 = 33518478
211 + 33518267 = 33518478

Showing the first eight; more decompositions exist.
