Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467848, here are decompositions:

19 + 31467829 = 31467848
37 + 31467811 = 31467848
127 + 31467721 = 31467848
157 + 31467691 = 31467848
277 + 31467571 = 31467848
367 + 31467481 = 31467848
547 + 31467301 = 31467848
619 + 31467229 = 31467848

Showing the first eight; more decompositions exist.
