Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533598, here are decompositions:

11 + 31533587 = 31533598
17 + 31533581 = 31533598
101 + 31533497 = 31533598
137 + 31533461 = 31533598
149 + 31533449 = 31533598
167 + 31533431 = 31533598
227 + 31533371 = 31533598
389 + 31533209 = 31533598

Showing the first eight; more decompositions exist.
