Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547086, here are decompositions:

23 + 31547063 = 31547086
47 + 31547039 = 31547086
83 + 31547003 = 31547086
89 + 31546997 = 31547086
149 + 31546937 = 31547086
173 + 31546913 = 31547086
239 + 31546847 = 31547086
269 + 31546817 = 31547086

Showing the first eight; more decompositions exist.
