Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453712, here are decompositions:

13 + 31453699 = 31453712
61 + 31453651 = 31453712
211 + 31453501 = 31453712
229 + 31453483 = 31453712
379 + 31453333 = 31453712
463 + 31453249 = 31453712
541 + 31453171 = 31453712
571 + 31453141 = 31453712

Showing the first eight; more decompositions exist.
