Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456426, here are decompositions:

47 + 31456379 = 31456426
107 + 31456319 = 31456426
149 + 31456277 = 31456426
167 + 31456259 = 31456426
179 + 31456247 = 31456426
227 + 31456199 = 31456426
233 + 31456193 = 31456426
263 + 31456163 = 31456426

Showing the first eight; more decompositions exist.
