Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506166, here are decompositions:

17 + 31506149 = 31506166
47 + 31506119 = 31506166
137 + 31506029 = 31506166
173 + 31505993 = 31506166
227 + 31505939 = 31506166
239 + 31505927 = 31506166
257 + 31505909 = 31506166
353 + 31505813 = 31506166

Showing the first eight; more decompositions exist.
