Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31571076, here are decompositions:

13 + 31571063 = 31571076
29 + 31571047 = 31571076
37 + 31571039 = 31571076
59 + 31571017 = 31571076
67 + 31571009 = 31571076
79 + 31570997 = 31571076
83 + 31570993 = 31571076
127 + 31570949 = 31571076

Showing the first eight; more decompositions exist.
