Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559332, here are decompositions:

11 + 31559321 = 31559332
113 + 31559219 = 31559332
239 + 31559093 = 31559332
251 + 31559081 = 31559332
263 + 31559069 = 31559332
281 + 31559051 = 31559332
359 + 31558973 = 31559332
449 + 31558883 = 31559332

Showing the first eight; more decompositions exist.
