Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33540380, here are decompositions:

7 + 33540373 = 33540380
37 + 33540343 = 33540380
73 + 33540307 = 33540380
103 + 33540277 = 33540380
127 + 33540253 = 33540380
151 + 33540229 = 33540380
241 + 33540139 = 33540380
277 + 33540103 = 33540380

Showing the first eight; more decompositions exist.
