Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543566, here are decompositions:

23 + 31543543 = 31543566
37 + 31543529 = 31543566
113 + 31543453 = 31543566
137 + 31543429 = 31543566
293 + 31543273 = 31543566
347 + 31543219 = 31543566
349 + 31543217 = 31543566
359 + 31543207 = 31543566

Showing the first eight; more decompositions exist.
