Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589512, here are decompositions:

29 + 31589483 = 31589512
89 + 31589423 = 31589512
173 + 31589339 = 31589512
179 + 31589333 = 31589512
191 + 31589321 = 31589512
443 + 31589069 = 31589512
569 + 31588943 = 31589512
839 + 31588673 = 31589512

Showing the first eight; more decompositions exist.
