Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456016, here are decompositions:

3 + 31456013 = 31456016
13 + 31456003 = 31456016
127 + 31455889 = 31456016
139 + 31455877 = 31456016
157 + 31455859 = 31456016
313 + 31455703 = 31456016
367 + 31455649 = 31456016
379 + 31455637 = 31456016

Showing the first eight; more decompositions exist.
