Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500852, here are decompositions:

43 + 31500809 = 31500852
59 + 31500793 = 31500852
79 + 31500773 = 31500852
139 + 31500713 = 31500852
151 + 31500701 = 31500852
193 + 31500659 = 31500852
241 + 31500611 = 31500852
263 + 31500589 = 31500852

Showing the first eight; more decompositions exist.
