Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31570360, here are decompositions:

23 + 31570337 = 31570360
47 + 31570313 = 31570360
71 + 31570289 = 31570360
137 + 31570223 = 31570360
149 + 31570211 = 31570360
167 + 31570193 = 31570360
197 + 31570163 = 31570360
257 + 31570103 = 31570360

Showing the first eight; more decompositions exist.
