Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547110, here are decompositions:

17 + 31547093 = 31547110
47 + 31547063 = 31547110
71 + 31547039 = 31547110
107 + 31547003 = 31547110
113 + 31546997 = 31547110
173 + 31546937 = 31547110
197 + 31546913 = 31547110
263 + 31546847 = 31547110

Showing the first eight; more decompositions exist.
