Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543356, here are decompositions:

7 + 31543349 = 31543356
83 + 31543273 = 31543356
113 + 31543243 = 31543356
137 + 31543219 = 31543356
139 + 31543217 = 31543356
149 + 31543207 = 31543356
193 + 31543163 = 31543356
223 + 31543133 = 31543356

Showing the first eight; more decompositions exist.
