Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31570174, here are decompositions:

3 + 31570171 = 31570174
11 + 31570163 = 31570174
17 + 31570157 = 31570174
23 + 31570151 = 31570174
71 + 31570103 = 31570174
131 + 31570043 = 31570174
191 + 31569983 = 31570174
197 + 31569977 = 31570174

Showing the first eight; more decompositions exist.
