Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531452, here are decompositions:

31 + 31531421 = 31531452
53 + 31531399 = 31531452
83 + 31531369 = 31531452
149 + 31531303 = 31531452
151 + 31531301 = 31531452
179 + 31531273 = 31531452
181 + 31531271 = 31531452
191 + 31531261 = 31531452

Showing the first eight; more decompositions exist.
