Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31571054, here are decompositions:

7 + 31571047 = 31571054
37 + 31571017 = 31571054
61 + 31570993 = 31571054
181 + 31570873 = 31571054
211 + 31570843 = 31571054
223 + 31570831 = 31571054
547 + 31570507 = 31571054
607 + 31570447 = 31571054

Showing the first eight; more decompositions exist.
