Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31570296, here are decompositions:

5 + 31570291 = 31570296
7 + 31570289 = 31570296
47 + 31570249 = 31570296
73 + 31570223 = 31570296
103 + 31570193 = 31570296
137 + 31570159 = 31570296
139 + 31570157 = 31570296
179 + 31570117 = 31570296

Showing the first eight; more decompositions exist.
