Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456010, here are decompositions:

7 + 31456003 = 31456010
109 + 31455901 = 31456010
151 + 31455859 = 31456010
181 + 31455829 = 31456010
283 + 31455727 = 31456010
307 + 31455703 = 31456010
373 + 31455637 = 31456010
379 + 31455631 = 31456010

Showing the first eight; more decompositions exist.
