Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453796, here are decompositions:

13 + 31453783 = 31453796
97 + 31453699 = 31453796
313 + 31453483 = 31453796
349 + 31453447 = 31453796
463 + 31453333 = 31453796
547 + 31453249 = 31453796
757 + 31453039 = 31453796
823 + 31452973 = 31453796

Showing the first eight; more decompositions exist.
