Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595612, here are decompositions:

19 + 31595593 = 31595612
31 + 31595581 = 31595612
43 + 31595569 = 31595612
229 + 31595383 = 31595612
241 + 31595371 = 31595612
439 + 31595173 = 31595612
613 + 31594999 = 31595612
709 + 31594903 = 31595612

Showing the first eight; more decompositions exist.
