Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595604, here are decompositions:

11 + 31595593 = 31595604
23 + 31595581 = 31595604
31 + 31595573 = 31595604
37 + 31595567 = 31595604
137 + 31595467 = 31595604
197 + 31595407 = 31595604
211 + 31595393 = 31595604
233 + 31595371 = 31595604

Showing the first eight; more decompositions exist.
