Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31572024, here are decompositions:

7 + 31572017 = 31572024
17 + 31572007 = 31572024
31 + 31571993 = 31572024
41 + 31571983 = 31572024
61 + 31571963 = 31572024
67 + 31571957 = 31572024
137 + 31571887 = 31572024
157 + 31571867 = 31572024

Showing the first eight; more decompositions exist.
