Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31570522, here are decompositions:

3 + 31570519 = 31570522
23 + 31570499 = 31570522
41 + 31570481 = 31570522
131 + 31570391 = 31570522
149 + 31570373 = 31570522
233 + 31570289 = 31570522
311 + 31570211 = 31570522
359 + 31570163 = 31570522

Showing the first eight; more decompositions exist.
