Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467380, here are decompositions:

13 + 31467367 = 31467380
79 + 31467301 = 31467380
151 + 31467229 = 31467380
181 + 31467199 = 31467380
199 + 31467181 = 31467380
211 + 31467169 = 31467380
223 + 31467157 = 31467380
277 + 31467103 = 31467380

Showing the first eight; more decompositions exist.
