Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33540638, here are decompositions:

31 + 33540607 = 33540638
67 + 33540571 = 33540638
181 + 33540457 = 33540638
211 + 33540427 = 33540638
331 + 33540307 = 33540638
349 + 33540289 = 33540638
379 + 33540259 = 33540638
409 + 33540229 = 33540638

Showing the first eight; more decompositions exist.
