Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33540138, here are decompositions:

17 + 33540121 = 33540138
31 + 33540107 = 33540138
41 + 33540097 = 33540138
59 + 33540079 = 33540138
67 + 33540071 = 33540138
127 + 33540011 = 33540138
167 + 33539971 = 33540138
197 + 33539941 = 33540138

Showing the first eight; more decompositions exist.
