Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33540978, here are decompositions:

5 + 33540973 = 33540978
7 + 33540971 = 33540978
11 + 33540967 = 33540978
17 + 33540961 = 33540978
47 + 33540931 = 33540978
59 + 33540919 = 33540978
89 + 33540889 = 33540978
157 + 33540821 = 33540978

Showing the first eight; more decompositions exist.
