Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595412, here are decompositions:

5 + 31595407 = 31595412
19 + 31595393 = 31595412
29 + 31595383 = 31595412
41 + 31595371 = 31595412
139 + 31595273 = 31595412
193 + 31595219 = 31595412
223 + 31595189 = 31595412
239 + 31595173 = 31595412

Showing the first eight; more decompositions exist.
