Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31570294, here are decompositions:

3 + 31570291 = 31570294
5 + 31570289 = 31570294
71 + 31570223 = 31570294
83 + 31570211 = 31570294
101 + 31570193 = 31570294
131 + 31570163 = 31570294
137 + 31570157 = 31570294
191 + 31570103 = 31570294

Showing the first eight; more decompositions exist.
