Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31572064, here are decompositions:

5 + 31572059 = 31572064
23 + 31572041 = 31572064
47 + 31572017 = 31572064
71 + 31571993 = 31572064
101 + 31571963 = 31572064
107 + 31571957 = 31572064
197 + 31571867 = 31572064
317 + 31571747 = 31572064

Showing the first eight; more decompositions exist.
