Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33540372, here are decompositions:

13 + 33540359 = 33540372
29 + 33540343 = 33540372
83 + 33540289 = 33540372
113 + 33540259 = 33540372
163 + 33540209 = 33540372
179 + 33540193 = 33540372
233 + 33540139 = 33540372
251 + 33540121 = 33540372

Showing the first eight; more decompositions exist.
