Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31570264, here are decompositions:

3 + 31570261 = 31570264
41 + 31570223 = 31570264
53 + 31570211 = 31570264
71 + 31570193 = 31570264
101 + 31570163 = 31570264
107 + 31570157 = 31570264
113 + 31570151 = 31570264
251 + 31570013 = 31570264

Showing the first eight; more decompositions exist.
