Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453410, here are decompositions:

17 + 31453393 = 31453410
19 + 31453391 = 31453410
89 + 31453321 = 31453410
127 + 31453283 = 31453410
229 + 31453181 = 31453410
239 + 31453171 = 31453410
251 + 31453159 = 31453410
269 + 31453141 = 31453410

Showing the first eight; more decompositions exist.
