Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611322, here are decompositions:

3 + 31611319 = 31611322
11 + 31611311 = 31611322
23 + 31611299 = 31611322
233 + 31611089 = 31611322
293 + 31611029 = 31611322
311 + 31611011 = 31611322
593 + 31610729 = 31611322
599 + 31610723 = 31611322

Showing the first eight; more decompositions exist.
