Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465852, here are decompositions:

3 + 31465849 = 31465852
23 + 31465829 = 31465852
71 + 31465781 = 31465852
179 + 31465673 = 31465852
191 + 31465661 = 31465852
233 + 31465619 = 31465852
251 + 31465601 = 31465852
281 + 31465571 = 31465852

Showing the first eight; more decompositions exist.
