Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489026, here are decompositions:

17 + 31489009 = 31489026
47 + 31488979 = 31489026
67 + 31488959 = 31489026
109 + 31488917 = 31489026
167 + 31488859 = 31489026
199 + 31488827 = 31489026
227 + 31488799 = 31489026
229 + 31488797 = 31489026

Showing the first eight; more decompositions exist.
