Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33540942, here are decompositions:

11 + 33540931 = 33540942
23 + 33540919 = 33540942
41 + 33540901 = 33540942
53 + 33540889 = 33540942
131 + 33540811 = 33540942
179 + 33540763 = 33540942
229 + 33540713 = 33540942
251 + 33540691 = 33540942

Showing the first eight; more decompositions exist.
