Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33540072, here are decompositions:

19 + 33540053 = 33540072
61 + 33540011 = 33540072
89 + 33539983 = 33540072
101 + 33539971 = 33540072
131 + 33539941 = 33540072
179 + 33539893 = 33540072
199 + 33539873 = 33540072
331 + 33539741 = 33540072

Showing the first eight; more decompositions exist.
