Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467458, here are decompositions:

157 + 31467301 = 31467458
199 + 31467259 = 31467458
229 + 31467229 = 31467458
277 + 31467181 = 31467458
331 + 31467127 = 31467458
601 + 31466857 = 31467458
709 + 31466749 = 31467458
727 + 31466731 = 31467458

Showing the first eight; more decompositions exist.
