Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543452, here are decompositions:

23 + 31543429 = 31543452
103 + 31543349 = 31543452
151 + 31543301 = 31543452
179 + 31543273 = 31543452
229 + 31543223 = 31543452
233 + 31543219 = 31543452
271 + 31543181 = 31543452
349 + 31543103 = 31543452

Showing the first eight; more decompositions exist.
