Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31570050, here are decompositions:

7 + 31570043 = 31570050
37 + 31570013 = 31570050
67 + 31569983 = 31570050
73 + 31569977 = 31570050
97 + 31569953 = 31570050
107 + 31569943 = 31570050
167 + 31569883 = 31570050
191 + 31569859 = 31570050

Showing the first eight; more decompositions exist.
