Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31570012, here are decompositions:

29 + 31569983 = 31570012
59 + 31569953 = 31570012
251 + 31569761 = 31570012
311 + 31569701 = 31570012
431 + 31569581 = 31570012
443 + 31569569 = 31570012
521 + 31569491 = 31570012
563 + 31569449 = 31570012

Showing the first eight; more decompositions exist.
