Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547322, here are decompositions:

5 + 31547317 = 31547322
19 + 31547303 = 31547322
41 + 31547281 = 31547322
61 + 31547261 = 31547322
113 + 31547209 = 31547322
179 + 31547143 = 31547322
193 + 31547129 = 31547322
229 + 31547093 = 31547322

Showing the first eight; more decompositions exist.
