Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33540578, here are decompositions:

7 + 33540571 = 33540578
61 + 33540517 = 33540578
151 + 33540427 = 33540578
157 + 33540421 = 33540578
271 + 33540307 = 33540578
349 + 33540229 = 33540578
439 + 33540139 = 33540578
457 + 33540121 = 33540578

Showing the first eight; more decompositions exist.
