Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33540642, here are decompositions:

19 + 33540623 = 33540642
61 + 33540581 = 33540642
71 + 33540571 = 33540642
89 + 33540553 = 33540642
103 + 33540539 = 33540642
139 + 33540503 = 33540642
181 + 33540461 = 33540642
229 + 33540413 = 33540642

Showing the first eight; more decompositions exist.
