Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595752, here are decompositions:

29 + 31595723 = 31595752
179 + 31595573 = 31595752
269 + 31595483 = 31595752
359 + 31595393 = 31595752
389 + 31595363 = 31595752
479 + 31595273 = 31595752
509 + 31595243 = 31595752
563 + 31595189 = 31595752

Showing the first eight; more decompositions exist.
