Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589234, here are decompositions:

37 + 31589197 = 31589234
67 + 31589167 = 31589234
97 + 31589137 = 31589234
223 + 31589011 = 31589234
241 + 31588993 = 31589234
277 + 31588957 = 31589234
283 + 31588951 = 31589234
307 + 31588927 = 31589234

Showing the first eight; more decompositions exist.
