Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453332, here are decompositions:

11 + 31453321 = 31453332
83 + 31453249 = 31453332
139 + 31453193 = 31453332
151 + 31453181 = 31453332
173 + 31453159 = 31453332
191 + 31453141 = 31453332
199 + 31453133 = 31453332
293 + 31453039 = 31453332

Showing the first eight; more decompositions exist.
