Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524, here are decompositions:

7 + 31517 = 31524
11 + 31513 = 31524
13 + 31511 = 31524
43 + 31481 = 31524
47 + 31477 = 31524
127 + 31397 = 31524
131 + 31393 = 31524
137 + 31387 = 31524

Showing the first eight; more decompositions exist.
