Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453412, here are decompositions:

19 + 31453393 = 31453412
79 + 31453333 = 31453412
163 + 31453249 = 31453412
241 + 31453171 = 31453412
271 + 31453141 = 31453412
373 + 31453039 = 31453412
439 + 31452973 = 31453412
619 + 31452793 = 31453412

Showing the first eight; more decompositions exist.
