Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547130, here are decompositions:

29 + 31547101 = 31547130
37 + 31547093 = 31547130
53 + 31547077 = 31547130
67 + 31547063 = 31547130
127 + 31547003 = 31547130
149 + 31546981 = 31547130
193 + 31546937 = 31547130
239 + 31546891 = 31547130

Showing the first eight; more decompositions exist.
