Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526, here are decompositions:

13 + 31513 = 31526
37 + 31489 = 31526
139 + 31387 = 31526
193 + 31333 = 31526
199 + 31327 = 31526
277 + 31249 = 31526
307 + 31219 = 31526
337 + 31189 = 31526

Showing the first eight; more decompositions exist.
