Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596388, here are decompositions:

71 + 31596317 = 31596388
179 + 31596209 = 31596388
269 + 31596119 = 31596388
347 + 31596041 = 31596388
359 + 31596029 = 31596388
419 + 31595969 = 31596388
521 + 31595867 = 31596388
557 + 31595831 = 31596388

Showing the first eight; more decompositions exist.
