Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33540668, here are decompositions:

61 + 33540607 = 33540668
97 + 33540571 = 33540668
151 + 33540517 = 33540668
211 + 33540457 = 33540668
241 + 33540427 = 33540668
277 + 33540391 = 33540668
379 + 33540289 = 33540668
409 + 33540259 = 33540668

Showing the first eight; more decompositions exist.
