Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467426, here are decompositions:

7 + 31467419 = 31467426
37 + 31467389 = 31467426
59 + 31467367 = 31467426
79 + 31467347 = 31467426
97 + 31467329 = 31467426
167 + 31467259 = 31467426
197 + 31467229 = 31467426
223 + 31467203 = 31467426

Showing the first eight; more decompositions exist.
