Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33518540, here are decompositions:

43 + 33518497 = 33518540
103 + 33518437 = 33518540
151 + 33518389 = 33518540
271 + 33518269 = 33518540
331 + 33518209 = 33518540
409 + 33518131 = 33518540
421 + 33518119 = 33518540
619 + 33517921 = 33518540

Showing the first eight; more decompositions exist.
