Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456410, here are decompositions:

31 + 31456379 = 31456410
79 + 31456331 = 31456410
131 + 31456279 = 31456410
151 + 31456259 = 31456410
163 + 31456247 = 31456410
173 + 31456237 = 31456410
191 + 31456219 = 31456410
211 + 31456199 = 31456410

Showing the first eight; more decompositions exist.
