Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33540672, here are decompositions:

13 + 33540659 = 33540672
101 + 33540571 = 33540672
211 + 33540461 = 33540672
251 + 33540421 = 33540672
281 + 33540391 = 33540672
313 + 33540359 = 33540672
383 + 33540289 = 33540672
419 + 33540253 = 33540672

Showing the first eight; more decompositions exist.
