Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31570362, here are decompositions:

59 + 31570303 = 31570362
71 + 31570291 = 31570362
73 + 31570289 = 31570362
101 + 31570261 = 31570362
113 + 31570249 = 31570362
139 + 31570223 = 31570362
151 + 31570211 = 31570362
191 + 31570171 = 31570362

Showing the first eight; more decompositions exist.
