Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589206, here are decompositions:

23 + 31589183 = 31589206
107 + 31589099 = 31589206
137 + 31589069 = 31589206
149 + 31589057 = 31589206
179 + 31589027 = 31589206
227 + 31588979 = 31589206
263 + 31588943 = 31589206
359 + 31588847 = 31589206

Showing the first eight; more decompositions exist.
