Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595606, here are decompositions:

13 + 31595593 = 31595606
37 + 31595569 = 31595606
139 + 31595467 = 31595606
199 + 31595407 = 31595606
223 + 31595383 = 31595606
397 + 31595209 = 31595606
433 + 31595173 = 31595606
547 + 31595059 = 31595606

Showing the first eight; more decompositions exist.
