Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31570670, here are decompositions:

3 + 31570667 = 31570670
67 + 31570603 = 31570670
151 + 31570519 = 31570670
163 + 31570507 = 31570670
211 + 31570459 = 31570670
223 + 31570447 = 31570670
367 + 31570303 = 31570670
379 + 31570291 = 31570670

Showing the first eight; more decompositions exist.
