Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456374, here are decompositions:

13 + 31456361 = 31456374
43 + 31456331 = 31456374
83 + 31456291 = 31456374
97 + 31456277 = 31456374
127 + 31456247 = 31456374
137 + 31456237 = 31456374
181 + 31456193 = 31456374
211 + 31456163 = 31456374

Showing the first eight; more decompositions exist.
