Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507026, here are decompositions:

17 + 31507009 = 31507026
53 + 31506973 = 31507026
97 + 31506929 = 31507026
139 + 31506887 = 31507026
197 + 31506829 = 31507026
227 + 31506799 = 31507026
233 + 31506793 = 31507026
277 + 31506749 = 31507026

Showing the first eight; more decompositions exist.
