Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33540572, here are decompositions:

19 + 33540553 = 33540572
151 + 33540421 = 33540572
181 + 33540391 = 33540572
199 + 33540373 = 33540572
229 + 33540343 = 33540572
283 + 33540289 = 33540572
313 + 33540259 = 33540572
379 + 33540193 = 33540572

Showing the first eight; more decompositions exist.
