Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31570176, here are decompositions:

5 + 31570171 = 31570176
13 + 31570163 = 31570176
17 + 31570159 = 31570176
19 + 31570157 = 31570176
59 + 31570117 = 31570176
73 + 31570103 = 31570176
89 + 31570087 = 31570176
163 + 31570013 = 31570176

Showing the first eight; more decompositions exist.
