Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467452, here are decompositions:

19 + 31467433 = 31467452
151 + 31467301 = 31467452
193 + 31467259 = 31467452
223 + 31467229 = 31467452
271 + 31467181 = 31467452
283 + 31467169 = 31467452
349 + 31467103 = 31467452
463 + 31466989 = 31467452

Showing the first eight; more decompositions exist.
