Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547170, here are decompositions:

23 + 31547147 = 31547170
41 + 31547129 = 31547170
107 + 31547063 = 31547170
131 + 31547039 = 31547170
167 + 31547003 = 31547170
173 + 31546997 = 31547170
233 + 31546937 = 31547170
257 + 31546913 = 31547170

Showing the first eight; more decompositions exist.
