Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547022, here are decompositions:

19 + 31547003 = 31547022
41 + 31546981 = 31547022
53 + 31546969 = 31547022
109 + 31546913 = 31547022
113 + 31546909 = 31547022
131 + 31546891 = 31547022
179 + 31546843 = 31547022
191 + 31546831 = 31547022

Showing the first eight; more decompositions exist.
