Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31570030, here are decompositions:

17 + 31570013 = 31570030
47 + 31569983 = 31570030
53 + 31569977 = 31570030
179 + 31569851 = 31570030
263 + 31569767 = 31570030
269 + 31569761 = 31570030
293 + 31569737 = 31570030
383 + 31569647 = 31570030

Showing the first eight; more decompositions exist.
