Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31570014, here are decompositions:

31 + 31569983 = 31570014
37 + 31569977 = 31570014
61 + 31569953 = 31570014
71 + 31569943 = 31570014
131 + 31569883 = 31570014
163 + 31569851 = 31570014
233 + 31569781 = 31570014
251 + 31569763 = 31570014

Showing the first eight; more decompositions exist.
