Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33518538, here are decompositions:

41 + 33518497 = 33518538
47 + 33518491 = 33518538
89 + 33518449 = 33518538
101 + 33518437 = 33518538
149 + 33518389 = 33518538
211 + 33518327 = 33518538
241 + 33518297 = 33518538
269 + 33518269 = 33518538

Showing the first eight; more decompositions exist.
