Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589688, here are decompositions:

5 + 31589683 = 31589688
29 + 31589659 = 31589688
127 + 31589561 = 31589688
149 + 31589539 = 31589688
227 + 31589461 = 31589688
281 + 31589407 = 31589688
311 + 31589377 = 31589688
349 + 31589339 = 31589688

Showing the first eight; more decompositions exist.
