Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31572096, here are decompositions:

13 + 31572083 = 31572096
37 + 31572059 = 31572096
47 + 31572049 = 31572096
67 + 31572029 = 31572096
79 + 31572017 = 31572096
89 + 31572007 = 31572096
103 + 31571993 = 31572096
113 + 31571983 = 31572096

Showing the first eight; more decompositions exist.
