Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31572010, here are decompositions:

3 + 31572007 = 31572010
17 + 31571993 = 31572010
47 + 31571963 = 31572010
53 + 31571957 = 31572010
131 + 31571879 = 31572010
233 + 31571777 = 31572010
263 + 31571747 = 31572010
311 + 31571699 = 31572010

Showing the first eight; more decompositions exist.
