Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529166, here are decompositions:

17 + 31529149 = 31529166
59 + 31529107 = 31529166
79 + 31529087 = 31529166
113 + 31529053 = 31529166
173 + 31528993 = 31529166
197 + 31528969 = 31529166
199 + 31528967 = 31529166
257 + 31528909 = 31529166

Showing the first eight; more decompositions exist.
