Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562454, here are decompositions:

5 + 31562449 = 31562454
13 + 31562441 = 31562454
23 + 31562431 = 31562454
31 + 31562423 = 31562454
97 + 31562357 = 31562454
107 + 31562347 = 31562454
163 + 31562291 = 31562454
173 + 31562281 = 31562454

Showing the first eight; more decompositions exist.
