Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456706, here are decompositions:

3 + 31456703 = 31456706
37 + 31456669 = 31456706
67 + 31456639 = 31456706
109 + 31456597 = 31456706
277 + 31456429 = 31456706
487 + 31456219 = 31456706
607 + 31456099 = 31456706
613 + 31456093 = 31456706

Showing the first eight; more decompositions exist.
