Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33540988, here are decompositions:

17 + 33540971 = 33540988
101 + 33540887 = 33540988
167 + 33540821 = 33540988
191 + 33540797 = 33540988
281 + 33540707 = 33540988
401 + 33540587 = 33540988
431 + 33540557 = 33540988
449 + 33540539 = 33540988

Showing the first eight; more decompositions exist.
