Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33490540, here are decompositions:

3 + 33490537 = 33490540
11 + 33490529 = 33490540
131 + 33490409 = 33490540
179 + 33490361 = 33490540
197 + 33490343 = 33490540
269 + 33490271 = 33490540
359 + 33490181 = 33490540
431 + 33490109 = 33490540

Showing the first eight; more decompositions exist.
