Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33540560, here are decompositions:

3 + 33540557 = 33540560
7 + 33540553 = 33540560
43 + 33540517 = 33540560
103 + 33540457 = 33540560
139 + 33540421 = 33540560
271 + 33540289 = 33540560
283 + 33540277 = 33540560
307 + 33540253 = 33540560

Showing the first eight; more decompositions exist.
