Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589582, here are decompositions:

43 + 31589539 = 31589582
109 + 31589473 = 31589582
181 + 31589401 = 31589582
223 + 31589359 = 31589582
229 + 31589353 = 31589582
331 + 31589251 = 31589582
463 + 31589119 = 31589582
571 + 31589011 = 31589582

Showing the first eight; more decompositions exist.
