Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31570834, here are decompositions:

3 + 31570831 = 31570834
5 + 31570829 = 31570834
17 + 31570817 = 31570834
23 + 31570811 = 31570834
47 + 31570787 = 31570834
167 + 31570667 = 31570834
257 + 31570577 = 31570834
353 + 31570481 = 31570834

Showing the first eight; more decompositions exist.
