Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475052, here are decompositions:

23 + 31475029 = 31475052
43 + 31475009 = 31475052
53 + 31474999 = 31475052
71 + 31474981 = 31475052
83 + 31474969 = 31475052
179 + 31474873 = 31475052
223 + 31474829 = 31475052
251 + 31474801 = 31475052

Showing the first eight; more decompositions exist.
