Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533418, here are decompositions:

5 + 31533413 = 31533418
29 + 31533389 = 31533418
47 + 31533371 = 31533418
149 + 31533269 = 31533418
227 + 31533191 = 31533418
251 + 31533167 = 31533418
269 + 31533149 = 31533418
317 + 31533101 = 31533418

Showing the first eight; more decompositions exist.
