Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589564, here are decompositions:

3 + 31589561 = 31589564
103 + 31589461 = 31589564
157 + 31589407 = 31589564
163 + 31589401 = 31589564
211 + 31589353 = 31589564
271 + 31589293 = 31589564
277 + 31589287 = 31589564
313 + 31589251 = 31589564

Showing the first eight; more decompositions exist.
