Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33540940, here are decompositions:

53 + 33540887 = 33540940
227 + 33540713 = 33540940
233 + 33540707 = 33540940
281 + 33540659 = 33540940
317 + 33540623 = 33540940
353 + 33540587 = 33540940
359 + 33540581 = 33540940
383 + 33540557 = 33540940

Showing the first eight; more decompositions exist.
