Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33540640, here are decompositions:

17 + 33540623 = 33540640
53 + 33540587 = 33540640
59 + 33540581 = 33540640
83 + 33540557 = 33540640
101 + 33540539 = 33540640
137 + 33540503 = 33540640
179 + 33540461 = 33540640
227 + 33540413 = 33540640

Showing the first eight; more decompositions exist.
