Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31570096, here are decompositions:

53 + 31570043 = 31570096
83 + 31570013 = 31570096
113 + 31569983 = 31570096
359 + 31569737 = 31570096
449 + 31569647 = 31570096
479 + 31569617 = 31570096
617 + 31569479 = 31570096
647 + 31569449 = 31570096

Showing the first eight; more decompositions exist.
