Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31570344, here are decompositions:

7 + 31570337 = 31570344
31 + 31570313 = 31570344
41 + 31570303 = 31570344
53 + 31570291 = 31570344
83 + 31570261 = 31570344
151 + 31570193 = 31570344
173 + 31570171 = 31570344
181 + 31570163 = 31570344

Showing the first eight; more decompositions exist.
