Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456344, here are decompositions:

13 + 31456331 = 31456344
53 + 31456291 = 31456344
67 + 31456277 = 31456344
97 + 31456247 = 31456344
103 + 31456241 = 31456344
107 + 31456237 = 31456344
151 + 31456193 = 31456344
181 + 31456163 = 31456344

Showing the first eight; more decompositions exist.
