Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585852, here are decompositions:

3 + 31585849 = 31585852
29 + 31585823 = 31585852
41 + 31585811 = 31585852
71 + 31585781 = 31585852
101 + 31585751 = 31585852
239 + 31585613 = 31585852
269 + 31585583 = 31585852
281 + 31585571 = 31585852

Showing the first eight; more decompositions exist.
