Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453352, here are decompositions:

19 + 31453333 = 31453352
31 + 31453321 = 31453352
103 + 31453249 = 31453352
181 + 31453171 = 31453352
193 + 31453159 = 31453352
211 + 31453141 = 31453352
313 + 31453039 = 31453352
331 + 31453021 = 31453352

Showing the first eight; more decompositions exist.
