Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471058, here are decompositions:

7 + 31471051 = 31471058
61 + 31470997 = 31471058
67 + 31470991 = 31471058
211 + 31470847 = 31471058
271 + 31470787 = 31471058
277 + 31470781 = 31471058
337 + 31470721 = 31471058
349 + 31470709 = 31471058

Showing the first eight; more decompositions exist.
