Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33540880, here are decompositions:

59 + 33540821 = 33540880
83 + 33540797 = 33540880
167 + 33540713 = 33540880
173 + 33540707 = 33540880
257 + 33540623 = 33540880
293 + 33540587 = 33540880
419 + 33540461 = 33540880
467 + 33540413 = 33540880

Showing the first eight; more decompositions exist.
