Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31571094, here are decompositions:

11 + 31571083 = 31571094
13 + 31571081 = 31571094
31 + 31571063 = 31571094
47 + 31571047 = 31571094
73 + 31571021 = 31571094
97 + 31570997 = 31571094
101 + 31570993 = 31571094
227 + 31570867 = 31571094

Showing the first eight; more decompositions exist.
