Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33540438, here are decompositions:

11 + 33540427 = 33540438
17 + 33540421 = 33540438
47 + 33540391 = 33540438
79 + 33540359 = 33540438
131 + 33540307 = 33540438
149 + 33540289 = 33540438
179 + 33540259 = 33540438
181 + 33540257 = 33540438

Showing the first eight; more decompositions exist.
