Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547206, here are decompositions:

3 + 31547203 = 31547206
29 + 31547177 = 31547206
59 + 31547147 = 31547206
113 + 31547093 = 31547206
167 + 31547039 = 31547206
269 + 31546937 = 31547206
293 + 31546913 = 31547206
359 + 31546847 = 31547206

Showing the first eight; more decompositions exist.
