Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595396, here are decompositions:

3 + 31595393 = 31595396
13 + 31595383 = 31595396
223 + 31595173 = 31595396
337 + 31595059 = 31595396
397 + 31594999 = 31595396
409 + 31594987 = 31595396
433 + 31594963 = 31595396
523 + 31594873 = 31595396

Showing the first eight; more decompositions exist.
