Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595588, here are decompositions:

7 + 31595581 = 31595588
19 + 31595569 = 31595588
181 + 31595407 = 31595588
337 + 31595251 = 31595588
379 + 31595209 = 31595588
487 + 31595101 = 31595588
601 + 31594987 = 31595588
727 + 31594861 = 31595588

Showing the first eight; more decompositions exist.
