Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453432, here are decompositions:

5 + 31453427 = 31453432
11 + 31453421 = 31453432
41 + 31453391 = 31453432
71 + 31453361 = 31453432
149 + 31453283 = 31453432
191 + 31453241 = 31453432
239 + 31453193 = 31453432
251 + 31453181 = 31453432

Showing the first eight; more decompositions exist.
