Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33540042, here are decompositions:

31 + 33540011 = 33540042
59 + 33539983 = 33540042
71 + 33539971 = 33540042
101 + 33539941 = 33540042
103 + 33539939 = 33540042
149 + 33539893 = 33540042
271 + 33539771 = 33540042
293 + 33539749 = 33540042

Showing the first eight; more decompositions exist.
