Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453416, here are decompositions:

23 + 31453393 = 31453416
83 + 31453333 = 31453416
149 + 31453267 = 31453416
167 + 31453249 = 31453416
223 + 31453193 = 31453416
257 + 31453159 = 31453416
283 + 31453133 = 31453416
439 + 31452977 = 31453416

Showing the first eight; more decompositions exist.
