Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465926, here are decompositions:

47 + 31465879 = 31465926
97 + 31465829 = 31465926
137 + 31465789 = 31465926
179 + 31465747 = 31465926
199 + 31465727 = 31465926
229 + 31465697 = 31465926
263 + 31465663 = 31465926
277 + 31465649 = 31465926

Showing the first eight; more decompositions exist.
