Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464834, here are decompositions:

7 + 31464827 = 31464834
13 + 31464821 = 31464834
47 + 31464787 = 31464834
53 + 31464781 = 31464834
103 + 31464731 = 31464834
257 + 31464577 = 31464834
263 + 31464571 = 31464834
277 + 31464557 = 31464834

Showing the first eight; more decompositions exist.
