Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600970, here are decompositions:

13 + 31600957 = 31600970
109 + 31600861 = 31600970
127 + 31600843 = 31600970
199 + 31600771 = 31600970
229 + 31600741 = 31600970
277 + 31600693 = 31600970
307 + 31600663 = 31600970
421 + 31600549 = 31600970

Showing the first eight; more decompositions exist.
