Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31571068, here are decompositions:

5 + 31571063 = 31571068
29 + 31571039 = 31571068
47 + 31571021 = 31571068
59 + 31571009 = 31571068
71 + 31570997 = 31571068
107 + 31570961 = 31571068
149 + 31570919 = 31571068
239 + 31570829 = 31571068

Showing the first eight; more decompositions exist.
