Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533538, here are decompositions:

5 + 31533533 = 31533538
41 + 31533497 = 31533538
89 + 31533449 = 31533538
107 + 31533431 = 31533538
149 + 31533389 = 31533538
167 + 31533371 = 31533538
269 + 31533269 = 31533538
347 + 31533191 = 31533538

Showing the first eight; more decompositions exist.
