Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453458, here are decompositions:

11 + 31453447 = 31453458
31 + 31453427 = 31453458
37 + 31453421 = 31453458
67 + 31453391 = 31453458
97 + 31453361 = 31453458
137 + 31453321 = 31453458
191 + 31453267 = 31453458
251 + 31453207 = 31453458

Showing the first eight; more decompositions exist.
