Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589326, here are decompositions:

5 + 31589321 = 31589326
23 + 31589303 = 31589326
29 + 31589297 = 31589326
227 + 31589099 = 31589326
239 + 31589087 = 31589326
257 + 31589069 = 31589326
269 + 31589057 = 31589326
347 + 31588979 = 31589326

Showing the first eight; more decompositions exist.
