Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589154, here are decompositions:

17 + 31589137 = 31589154
67 + 31589087 = 31589154
97 + 31589057 = 31589154
127 + 31589027 = 31589154
137 + 31589017 = 31589154
197 + 31588957 = 31589154
211 + 31588943 = 31589154
227 + 31588927 = 31589154

Showing the first eight; more decompositions exist.
