Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467422, here are decompositions:

3 + 31467419 = 31467422
163 + 31467259 = 31467422
193 + 31467229 = 31467422
223 + 31467199 = 31467422
241 + 31467181 = 31467422
433 + 31466989 = 31467422
523 + 31466899 = 31467422
601 + 31466821 = 31467422

Showing the first eight; more decompositions exist.
