Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547146, here are decompositions:

3 + 31547143 = 31547146
17 + 31547129 = 31547146
53 + 31547093 = 31547146
83 + 31547063 = 31547146
107 + 31547039 = 31547146
149 + 31546997 = 31547146
233 + 31546913 = 31547146
347 + 31546799 = 31547146

Showing the first eight; more decompositions exist.
