Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527852, here are decompositions:

23 + 31527829 = 31527852
71 + 31527781 = 31527852
149 + 31527703 = 31527852
151 + 31527701 = 31527852
163 + 31527689 = 31527852
193 + 31527659 = 31527852
269 + 31527583 = 31527852
283 + 31527569 = 31527852

Showing the first eight; more decompositions exist.
