Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523454, here are decompositions:

13 + 31523441 = 31523454
43 + 31523411 = 31523454
47 + 31523407 = 31523454
73 + 31523381 = 31523454
107 + 31523347 = 31523454
211 + 31523243 = 31523454
223 + 31523231 = 31523454
227 + 31523227 = 31523454

Showing the first eight; more decompositions exist.
