Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31570332, here are decompositions:

19 + 31570313 = 31570332
29 + 31570303 = 31570332
41 + 31570291 = 31570332
43 + 31570289 = 31570332
71 + 31570261 = 31570332
83 + 31570249 = 31570332
109 + 31570223 = 31570332
113 + 31570219 = 31570332

Showing the first eight; more decompositions exist.
