Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33540680, here are decompositions:

73 + 33540607 = 33540680
109 + 33540571 = 33540680
127 + 33540553 = 33540680
163 + 33540517 = 33540680
223 + 33540457 = 33540680
307 + 33540373 = 33540680
337 + 33540343 = 33540680
373 + 33540307 = 33540680

Showing the first eight; more decompositions exist.
