Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598166, here are decompositions:

23 + 31598143 = 31598166
29 + 31598137 = 31598166
109 + 31598057 = 31598166
137 + 31598029 = 31598166
139 + 31598027 = 31598166
157 + 31598009 = 31598166
179 + 31597987 = 31598166
233 + 31597933 = 31598166

Showing the first eight; more decompositions exist.
