Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453404, here are decompositions:

11 + 31453393 = 31453404
13 + 31453391 = 31453404
43 + 31453361 = 31453404
71 + 31453333 = 31453404
83 + 31453321 = 31453404
137 + 31453267 = 31453404
163 + 31453241 = 31453404
197 + 31453207 = 31453404

Showing the first eight; more decompositions exist.
