Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31571060, here are decompositions:

13 + 31571047 = 31571060
43 + 31571017 = 31571060
61 + 31570999 = 31571060
67 + 31570993 = 31571060
151 + 31570909 = 31571060
193 + 31570867 = 31571060
229 + 31570831 = 31571060
457 + 31570603 = 31571060

Showing the first eight; more decompositions exist.
