Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456196, here are decompositions:

3 + 31456193 = 31456196
73 + 31456123 = 31456196
97 + 31456099 = 31456196
103 + 31456093 = 31456196
193 + 31456003 = 31456196
307 + 31455889 = 31456196
337 + 31455859 = 31456196
367 + 31455829 = 31456196

Showing the first eight; more decompositions exist.
