Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543434, here are decompositions:

5 + 31543429 = 31543434
37 + 31543397 = 31543434
73 + 31543361 = 31543434
103 + 31543331 = 31543434
191 + 31543243 = 31543434
211 + 31543223 = 31543434
227 + 31543207 = 31543434
271 + 31543163 = 31543434

Showing the first eight; more decompositions exist.
