Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593556, here are decompositions:

3 + 31593553 = 31593556
23 + 31593533 = 31593556
53 + 31593503 = 31593556
167 + 31593389 = 31593556
179 + 31593377 = 31593556
257 + 31593299 = 31593556
359 + 31593197 = 31593556
383 + 31593173 = 31593556

Showing the first eight; more decompositions exist.
