Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547116, here are decompositions:

23 + 31547093 = 31547116
53 + 31547063 = 31547116
113 + 31547003 = 31547116
179 + 31546937 = 31547116
269 + 31546847 = 31547116
317 + 31546799 = 31547116
479 + 31546637 = 31547116
563 + 31546553 = 31547116

Showing the first eight; more decompositions exist.
