Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589706, here are decompositions:

13 + 31589693 = 31589706
23 + 31589683 = 31589706
47 + 31589659 = 31589706
73 + 31589633 = 31589706
139 + 31589567 = 31589706
167 + 31589539 = 31589706
193 + 31589513 = 31589706
223 + 31589483 = 31589706

Showing the first eight; more decompositions exist.
