Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516852, here are decompositions:

11 + 31516841 = 31516852
41 + 31516811 = 31516852
71 + 31516781 = 31516852
149 + 31516703 = 31516852
233 + 31516619 = 31516852
239 + 31516613 = 31516852
281 + 31516571 = 31516852
293 + 31516559 = 31516852

Showing the first eight; more decompositions exist.
