Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527166, here are decompositions:

17 + 31527149 = 31527166
23 + 31527143 = 31527166
59 + 31527107 = 31527166
89 + 31527077 = 31527166
149 + 31527017 = 31527166
227 + 31526939 = 31527166
239 + 31526927 = 31527166
263 + 31526903 = 31527166

Showing the first eight; more decompositions exist.
