Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595574, here are decompositions:

5 + 31595569 = 31595574
7 + 31595567 = 31595574
107 + 31595467 = 31595574
167 + 31595407 = 31595574
181 + 31595393 = 31595574
191 + 31595383 = 31595574
211 + 31595363 = 31595574
331 + 31595243 = 31595574

Showing the first eight; more decompositions exist.
