Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33540144, here are decompositions:

5 + 33540139 = 33540144
23 + 33540121 = 33540144
37 + 33540107 = 33540144
41 + 33540103 = 33540144
47 + 33540097 = 33540144
61 + 33540083 = 33540144
73 + 33540071 = 33540144
167 + 33539977 = 33540144

Showing the first eight; more decompositions exist.
