Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31571044, here are decompositions:

5 + 31571039 = 31571044
23 + 31571021 = 31571044
47 + 31570997 = 31571044
83 + 31570961 = 31571044
137 + 31570907 = 31571044
227 + 31570817 = 31571044
233 + 31570811 = 31571044
257 + 31570787 = 31571044

Showing the first eight; more decompositions exist.
