Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547166, here are decompositions:

5 + 31547161 = 31547166
19 + 31547147 = 31547166
23 + 31547143 = 31547166
37 + 31547129 = 31547166
73 + 31547093 = 31547166
89 + 31547077 = 31547166
103 + 31547063 = 31547166
127 + 31547039 = 31547166

Showing the first eight; more decompositions exist.
