Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595570, here are decompositions:

3 + 31595567 = 31595570
103 + 31595467 = 31595570
163 + 31595407 = 31595570
199 + 31595371 = 31595570
397 + 31595173 = 31595570
571 + 31594999 = 31595570
607 + 31594963 = 31595570
709 + 31594861 = 31595570

Showing the first eight; more decompositions exist.
