Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472196, here are decompositions:

5 + 31472191 = 31472196
13 + 31472183 = 31472196
17 + 31472179 = 31472196
29 + 31472167 = 31472196
37 + 31472159 = 31472196
43 + 31472153 = 31472196
47 + 31472149 = 31472196
53 + 31472143 = 31472196

Showing the first eight; more decompositions exist.
