Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31571196, here are decompositions:

5 + 31571191 = 31571196
29 + 31571167 = 31571196
47 + 31571149 = 31571196
53 + 31571143 = 31571196
113 + 31571083 = 31571196
149 + 31571047 = 31571196
157 + 31571039 = 31571196
179 + 31571017 = 31571196

Showing the first eight; more decompositions exist.
