Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593322, here are decompositions:

23 + 31593299 = 31593322
71 + 31593251 = 31593322
149 + 31593173 = 31593322
311 + 31593011 = 31593322
401 + 31592921 = 31593322
479 + 31592843 = 31593322
659 + 31592663 = 31593322
701 + 31592621 = 31593322

Showing the first eight; more decompositions exist.
