Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589662, here are decompositions:

3 + 31589659 = 31589662
29 + 31589633 = 31589662
101 + 31589561 = 31589662
149 + 31589513 = 31589662
179 + 31589483 = 31589662
239 + 31589423 = 31589662
359 + 31589303 = 31589662
479 + 31589183 = 31589662

Showing the first eight; more decompositions exist.
