Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31706, here are decompositions:

7 + 31699 = 31706
19 + 31687 = 31706
43 + 31663 = 31706
79 + 31627 = 31706
139 + 31567 = 31706
163 + 31543 = 31706
193 + 31513 = 31706
229 + 31477 = 31706

Showing the first eight; more decompositions exist.
