Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31570134, here are decompositions:

17 + 31570117 = 31570134
23 + 31570111 = 31570134
31 + 31570103 = 31570134
47 + 31570087 = 31570134
53 + 31570081 = 31570134
151 + 31569983 = 31570134
157 + 31569977 = 31570134
181 + 31569953 = 31570134

Showing the first eight; more decompositions exist.
