Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456052, here are decompositions:

31 + 31456021 = 31456052
151 + 31455901 = 31456052
163 + 31455889 = 31456052
193 + 31455859 = 31456052
211 + 31455841 = 31456052
223 + 31455829 = 31456052
349 + 31455703 = 31456052
421 + 31455631 = 31456052

Showing the first eight; more decompositions exist.
