Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31570006, here are decompositions:

23 + 31569983 = 31570006
29 + 31569977 = 31570006
53 + 31569953 = 31570006
239 + 31569767 = 31570006
269 + 31569737 = 31570006
317 + 31569689 = 31570006
359 + 31569647 = 31570006
389 + 31569617 = 31570006

Showing the first eight; more decompositions exist.
