Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31571434, here are decompositions:

53 + 31571381 = 31571434
101 + 31571333 = 31571434
107 + 31571327 = 31571434
131 + 31571303 = 31571434
227 + 31571207 = 31571434
233 + 31571201 = 31571434
353 + 31571081 = 31571434
617 + 31570817 = 31571434

Showing the first eight; more decompositions exist.
