Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33540738, here are decompositions:

31 + 33540707 = 33540738
41 + 33540697 = 33540738
47 + 33540691 = 33540738
79 + 33540659 = 33540738
131 + 33540607 = 33540738
151 + 33540587 = 33540738
157 + 33540581 = 33540738
167 + 33540571 = 33540738

Showing the first eight; more decompositions exist.
