Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31570662, here are decompositions:

43 + 31570619 = 31570662
59 + 31570603 = 31570662
163 + 31570499 = 31570662
181 + 31570481 = 31570662
271 + 31570391 = 31570662
283 + 31570379 = 31570662
349 + 31570313 = 31570662
359 + 31570303 = 31570662

Showing the first eight; more decompositions exist.
