Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31572076, here are decompositions:

17 + 31572059 = 31572076
47 + 31572029 = 31572076
59 + 31572017 = 31572076
83 + 31571993 = 31572076
113 + 31571963 = 31572076
197 + 31571879 = 31572076
227 + 31571849 = 31572076
449 + 31571627 = 31572076

Showing the first eight; more decompositions exist.
