Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31570150, here are decompositions:

47 + 31570103 = 31570150
107 + 31570043 = 31570150
137 + 31570013 = 31570150
167 + 31569983 = 31570150
173 + 31569977 = 31570150
197 + 31569953 = 31570150
383 + 31569767 = 31570150
389 + 31569761 = 31570150

Showing the first eight; more decompositions exist.
