Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33518440, here are decompositions:

3 + 33518437 = 33518440
23 + 33518417 = 33518440
47 + 33518393 = 33518440
89 + 33518351 = 33518440
107 + 33518333 = 33518440
113 + 33518327 = 33518440
167 + 33518273 = 33518440
173 + 33518267 = 33518440

Showing the first eight; more decompositions exist.
