Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33540140, here are decompositions:

19 + 33540121 = 33540140
37 + 33540103 = 33540140
43 + 33540097 = 33540140
61 + 33540079 = 33540140
157 + 33539983 = 33540140
163 + 33539977 = 33540140
199 + 33539941 = 33540140
397 + 33539743 = 33540140

Showing the first eight; more decompositions exist.
