Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456022, here are decompositions:

19 + 31456003 = 31456022
61 + 31455961 = 31456022
163 + 31455859 = 31456022
181 + 31455841 = 31456022
193 + 31455829 = 31456022
271 + 31455751 = 31456022
373 + 31455649 = 31456022
523 + 31455499 = 31456022

Showing the first eight; more decompositions exist.
