Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589598, here are decompositions:

31 + 31589567 = 31589598
37 + 31589561 = 31589598
59 + 31589539 = 31589598
137 + 31589461 = 31589598
191 + 31589407 = 31589598
197 + 31589401 = 31589598
239 + 31589359 = 31589598
269 + 31589329 = 31589598

Showing the first eight; more decompositions exist.
