Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33540648, here are decompositions:

41 + 33540607 = 33540648
61 + 33540587 = 33540648
67 + 33540581 = 33540648
109 + 33540539 = 33540648
131 + 33540517 = 33540648
191 + 33540457 = 33540648
227 + 33540421 = 33540648
257 + 33540391 = 33540648

Showing the first eight; more decompositions exist.
