Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607026, here are decompositions:

29 + 31606997 = 31607026
47 + 31606979 = 31607026
53 + 31606973 = 31607026
83 + 31606943 = 31607026
107 + 31606919 = 31607026
179 + 31606847 = 31607026
197 + 31606829 = 31607026
359 + 31606667 = 31607026

Showing the first eight; more decompositions exist.
