Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33540442, here are decompositions:

29 + 33540413 = 33540442
83 + 33540359 = 33540442
191 + 33540251 = 33540442
233 + 33540209 = 33540442
359 + 33540083 = 33540442
389 + 33540053 = 33540442
431 + 33540011 = 33540442
491 + 33539951 = 33540442

Showing the first eight; more decompositions exist.
