Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31570024, here are decompositions:

11 + 31570013 = 31570024
41 + 31569983 = 31570024
47 + 31569977 = 31570024
71 + 31569953 = 31570024
173 + 31569851 = 31570024
257 + 31569767 = 31570024
263 + 31569761 = 31570024
383 + 31569641 = 31570024

Showing the first eight; more decompositions exist.
