Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589268, here are decompositions:

17 + 31589251 = 31589268
71 + 31589197 = 31589268
101 + 31589167 = 31589268
131 + 31589137 = 31589268
149 + 31589119 = 31589268
181 + 31589087 = 31589268
199 + 31589069 = 31589268
211 + 31589057 = 31589268

Showing the first eight; more decompositions exist.
