Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547164, here are decompositions:

3 + 31547161 = 31547164
17 + 31547147 = 31547164
71 + 31547093 = 31547164
101 + 31547063 = 31547164
167 + 31546997 = 31547164
227 + 31546937 = 31547164
251 + 31546913 = 31547164
317 + 31546847 = 31547164

Showing the first eight; more decompositions exist.
