Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547272, here are decompositions:

5 + 31547267 = 31547272
11 + 31547261 = 31547272
41 + 31547231 = 31547272
179 + 31547093 = 31547272
233 + 31547039 = 31547272
269 + 31547003 = 31547272
359 + 31546913 = 31547272
563 + 31546709 = 31547272

Showing the first eight; more decompositions exist.
