Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33540972, here are decompositions:

5 + 33540967 = 33540972
11 + 33540961 = 33540972
41 + 33540931 = 33540972
53 + 33540919 = 33540972
71 + 33540901 = 33540972
83 + 33540889 = 33540972
151 + 33540821 = 33540972
281 + 33540691 = 33540972

Showing the first eight; more decompositions exist.
